Excuse me for the delay -- i've got a lot of things i have to do
besides playing with flammable materials in USENET.
Well, i'll try to outline the rationale after my proposal.
First, let's define terms.
Localization is when a system is supposed to work with only one
(user's) language. In practice, bilinguality is required because
most programming languages and command-line interfaces heavily use
English mnemonics.
Localized system's components apriori know the language of the texts
they work with (including sorting/case conversion rules and, more
important the alphabet). Since the (supposedly small) alphabet is
used, there is no need to use multibyte characters (at least for
European and Slavic languages) and there are already national
standards in place. For Greek or Hebrew or Russian users Unicode/ISO10646
offers nothing except wasted disk space.
Therefore, i'm discarding all claims that Unicode/ISO10646 is intended
to provide means for localization ONLY. It is designed for
internationalization, i.e. for supporting sufficiently multilingual
environments; and this function is the only justification for
its introduction.
Now, i think everybody agrees that the "ultimate encoding" is
the one which provides the complete information about which
language is used -- it sovles all the problems.
Such an encoding can be implemented with:
1) register switching with (say) escape sequences.
This is highly impractical; moreover it is impossible
to determine the language if the information is available
from some point in the middle of file -- this situation
is especially troubling with Unix file pointer sharing.
2) every character code is a pair (language-code, letter-number-in-alphabet)
It is hardly practical because of the storage considerations.
Codifying languages require at least 10-12 bits, ie. every
letter turns into at least 3-byte sequence.
Now, we can sacrifice some information to achieve better compression
by assinging similar codes to similar LETTERS (note that i didn't
use the word GLYPH).
First we need to determine which information CAN be dropped without
making the encoding impractical.
Obviously, the visual representation (i.e. the set of glyphs) should
be preserved -- it sets the lower boundary on the compression.
Let's analyse the other properties of the ultimate encoding:
1) it explicitly distinguises between the natural languages.
This information cannot be used for processing the texts anyway
because machines do not *understand* languages and therefore
do not care about the contents. The language indication can
be useful for selecting a dictionary; but the words themselves
are already good indicators of the language (with few exceptions)
involved. Moreover, the spell-checking is usually done at the
input where the language in question is known.
I think this property can be easily dropped.
2) there is an *algorithm* for converting from upper case to lower case
and vice versa.
This property is extremely useful for everything involving
searches in texts and databases. The case-insensitive comparison
is simply inavoidable because of the rules of capitalization
in sentences (i.e. you can't easily tell if the word at the
beginning of sentence is capitalized because it is name or because
of the common rule). The database applications often require
preserving the strings as was entered while searching for
words with undefined capitalization.
If an encoding does not provide this property it is nearly
useless for most library/groupware and business applications.
Therefore this property MUST be preserved.
(I have to remark here that neither Unicode nor ISO 10646 provide
a way to perform case-insensitive comparison without specifying
the exact language of the string -- if the language is kept
OUTSIDE the text the text itself can be encoded within the
alpabet of this particular language much more effectively).
3) there is an *algorithm* for lexicographical sorting (and for
that matter for range comparisons).
This is necessary if the now-ubiquotus semantics of regular
expressions, shell globbing and sorted directories (and, of
course, neat sorted reports) is to be preserved.
Several people argued that this functionality is not actually
necessary because users will want to see strings sorted
accordingly to their native language's rules). While it is
a neat idea it still does not eliminate the necessity of a
generic algorithm used as fallback for "customized" sorting
algorithsm -- what, for example, is the idea of sorting Chinese
using rules of Finnish?
Moreover, the usage of a "unversal" algorithm is inavoidable
when consumers of the pre-sorted information do not share
a cultural background.
Therefore this property must be preserved as well.
4) indication of the language is useful for hyphenation.
There is no such thing as ideal hyphenation algorithms --
the hyphenation algorithms are nothing more than euristics
which yield more-less reasonable results.
While the high-quality hyphenation algorithms require
dictionaries and heavily use language specifics the
reasonable results (sufficient for use in, say, columns
of tables or as a base for consequtive manual reaarangement)
can be achieved by relatively generic algorithms based on
knowledge of specific roles of letters (i.e. vowels and
modificators like hard/soft signs in Russian).
Dictionary-based hyphenation algorithms do not need the
language specification because the words themselves indicate
the language; if the word is not in the dictionary the
generic rules should be applied.
Therefore it is desireable (though not necessary) that
the letter classes (ie. which ones are vowels) are preserved.
Fortunately, if a letter shared between languages it is
nearly certain that it is (is not) vowel in both languages.
5) typographical-quality fonts often differentiate between
"similar" glyhps reproducible on lower-resolution devices.
However, it is possible to create reasonably-looking fonts
shared between several languages if the basic graphic set
of the languages is common (say, Latin for European languages,
Cyrillic for most Slavic languages). Actually, it the way
the font designers work in the multi-lingual environments.
The proposed encoding methodology (see later) "automatically"
separates graphic sets, so the ability to output typography-
quality text is essentially "free" in the proposed encoding.
The way the ultimate encoding is compressed into the proposed
encoding is quite simple:
The alphabets are separated into several groups; in every group
conflicts between incompatible ordering resolved by duplicating
codes for the conflicting letters. If there are letters which do
not have upper/lowercase counterparts (like German eszat) new
codes should be reserved to distinguish the corresponding printable
signs as "special" (i.e. the special German S) or new glyphs should
be added (SS). If there is ambiguity in converting case (like
cyrillic/greek/german T) this glyph should be assigned several codes
to eliminate ambiguity. If a glyph can represent differntly-behaving
letters in different languages (like "o or l, c and h in Spanish) it
should be assigned several codes to eliminate the ambiguity.
The "canonical" sorting order is the _dictionary_ one (dictionaries
are usually more logical in their sorting conventions).
The criteria for separating alphabets into groups are simple as well -
it simply comparing the number of new codes which are introduced
by adding a new group with the number of new codes assigned by
attempting to fit the language in existing groups (well, it's not
that simple but still the problem is well-formalized and can be
solved with known mathematical methods without reverting to
truthsearching by voting).
It makes sense to keep codes in the order similar to the order of
letters in alphabet to eliminate the need for large tables used by
the universal sorting algortim. The canonical universal sorting algorithm
should be included in the standard (contrary to the popular opinion
it would not be THAT large -- i think everything can be fitted in
less than 50 lines because sorting irregularities are specific for
European languages for historical reasons [namely the idea of dictionary
with sorted entries is European -- and the irregular rules were
accepted before the importance of simple lexicographical sorting was
realized -- see Knuth vol.3], the sorting rules for ancient languages
were introduced _later_ as well as rules for languages which had no
established writing at the time (most of Cyrillic-based languages for example
had no written form before the nations were occupied by chauvinistic
Russian imperialists which obviously did not care about the culture
or ethnic miniorities and opressed them by inventing and introducing
writing to be able to give orders in natives' languages -- that's for
soc.culture.soviet readers).
The "customized" sorting algorithms (sorting everything Latin-based
according to, say, Finnish rules) in most cases can be reduced to
the universal sorting by trivial transliteration which makes possible
introduction of table-driven generic customized sorting routines.
Apparently it makes sense to violate the lexicographical letter
ordering for Latin-based languages to make the proposed encoding
upward-compatible with ASCII. The price is nothing more than
one additional transliteration table in the comparison/sorting algorithm.
Since the proposed encoding preserves the properties 2 & 3 of the
ultimate encoding it is POSSIBLE to create truly internationalized
applications without getting into local specifics (i.e. you can
sort German file on a machine in Japan without any changes in
environment). No additional off-text information is required which
surely allows to preserve the existing interfaces like regular
expressions/shell globbing/mailing systems etc and minimize changes
in the existing software.
To ease hypenation problem it may make sense to add a zero-width
"hyphenate hint" symbol (aka \% in troff). This symbol can be added
manually or by language-specific hyphenation algorithm at the
input (it may as well be a part of spell-checker, in this role
it is essentially "free"). The idea is to leave ALL language
specifics at the point of input where the language is supposedly
known. If a "generic" hypenation algorithm is included in standard
it may be possible to omit hyphenation hints in words which were
split correctly by the standard algorithm.
The main inconvinience introduced by the proposed encoding is
the possibility of confusion between several codes for a glyph.
However, since practically all input is done in a sinlge or two
languages it is not really a problem. Some people will object
to explicit switching between languages, however; it they LIKE
to include a foreign word into a letter as native it it supposed
to be treated as native. Introducing spell-checking at input
and emphasising selected languages by means of color, brightness
or different font styles practically eliminates the problem.
ISO 10646 (unlike Unicode as in Plan 9) already provides several
codes for identical glyphs in places where it is obviously
absurd to do otherwise (as with T in cyrillic, greek and latin);
but as old saying goes: "you can't be 30% pregnant". This
does not solve all sorting and case conversion problems (unlike the
systematic approach i outlined before) but introduces all
inconviniences of having ambiguous glyph encodings.
Now, flame mode on (type 'n' if you think the following material
can be offensive, tasteless or plain stupid):

Have it ever occured to you that texts may contain arbitrary numbers

Nobody (surely, not me) ever said something about getting everything
in the kernel. However, moving multilingual support from SYSTEM
software to APPLICATION software is the best way to kill the idea.
Somehow you forgot that what is not done once in system will be
done in zillion incompatibe ways in user programs. Take MS-DOS
as a live example.

If it IS the way the logic is taught here i feel pity for the

logic is a precise science and attempts to make "logical"

KOI-8 became a standard in early 70s and sure is codified (apparetly
not by ISO but by CCITT because it is based on "phonetical" system
for sending cyrillic messages over international talegraph which
predates computers).

One wonders on X.25, X.29, X.400 and a lot of other stuff which
was standartized BEFORE it become a proven practical solution.
Need i to remind that ASCII defeated EBCDIC in the market before
it become international standard.
As for ISO commitees -- USSR is surely was represented by petty
bureaucrats from the Ministry of Communications who are utterly
incompetent. Somehow international bodies never got interested
in looking for really competent people if they do not represent
government or corporate interests. Unfortunately we can do nothing
about it. The only remedy is to oppose attemts to standartize
things which gained no market acceptance.

How do think you're going to attribute a single language to the user avg?

As i already said Unicode/ISO 10646 are USELESS for localization
-- we don't need one more standard where old standards work
just fine.
>I believe that multinational documented will be the exception, not the

Learn some foreighn language and try to use it in the real-life
communications -- you'll find that mixed-language texts are
far far more common than you think. Russian, for example
do not have equivalents for "political correctness" or
"mentally disadvantaged" simply because that plague avoided
the Russian culture.

For "internationalization" as you understand it Unicode is
nothing more than extra bytes and lot of pain in the ass.

You don't need changes in file systems to support multilingual texts.
Having developed bilingual Unix i can assure you in that.

Renaming /etc or /etc/passwd in order to achieve "multinationalization"
is plain stupid because these aren't human words but rather kinds
of hierogliphs. Somehow French, Russian, German programmers never
had troubles understanding that IF THEN ELSE means conditional
excecution. It may be not so obvious for English speakers who
grow up on COBOL but the computerish semantic units are easier to
understand if not to mix them with the natural languages.
I bet that schoolchilden in Russia have much less troubles
understanding the difference between usage of conditional
clauses in natural and algorithmic languages (simply *because*
they're different).

It means only that you don't understand what multinationalization is.
I myself developed the system which is successfully used by
people knowing English or Russian for a decade -- somehow it
didn't collapsed.
To make system multinational you don't need to rename system
utilities and files. Waht you need is to give users:
- ability to operate texts in their own language
- print diagnostic messages in user's language
- provide documentation in user's language
- provide means for development of multinational applications
(i.e. make development tools to understand the user's language)
- support filenames in user's language
- provide a way to customize user's environment (aka aliases)
Unix already has adequate customization mechanizms.

Tell it to the secretary in DEMOS -- she somehow used to keep
her whole stuff in a Unix machine for years without bothering
to learn any English. What you think is impossible or of
questionable utility is already used by lots of people for
many many years.

Ever heard about string files? It is as easy as that.
You may also want to steal a look at Macintrash -- they had
it from the very beginning.

No logic here. Having several codes for a glyph does not
hinder application's ability to treat that as a glyph.

Ah. Checked your logic lately? Tell the Russian users they'll
need two bytes per letter instead of one to be able to do
what they already can do with KOI-8 (well, not exactly; they'll
be unable to sort without telling which language they mean).
The bi-lingual encodings with pairs of separate alphabets
fitting in one byte (or fitting in two bytes for Chinese and
Japanese) are quite sufficient for localization; and moreover
there already are standards.

Aha. I like your naivete. The fastest way to achieve the "changes"
is to butcher every ex-communist official. Sure, Russian users
will pay the price -- to companies which will offer them useable
products which do not follow dead-born standards.

I always thought that the hyphenation routine's place is in the
SYSTEM library. It's a reuseable piece of code. And there is
a lot of places where strings need to be hyphenated (long diagnostics
in windows of variable size) even by trivial programs.
The behaviour of Unix utilities simply wrapping strings over
the right edge is at the best case a kludge. I somehow hope
that it'll change.

The second and the third sentences have no logical link.
Sure Unicode does not help for word processing.

Somehow i use to print documents in both Russian and English without
bothering to switch fonts. If Unicode does not allow me to do that
i simply never switch to it (as well as many other users).
I don't need to spend disk space for the benefit of being unable
to do things i used to for years.

Globbing is nothing more than sequential matching to a regular expression.

If processing is done using localized (non-Unicode) form then
why do we need Unicode at all?
The assertion that the multilingual processing requires
register-switching (aka "fancy mode") is simply wrong.

Then forget about Unicode. It is not supposed to be a mean of
localization.

I worry why don't you run around crying that Unix require
record-oriented files and defacto attribution of text vs other
files. You'd better think before posting anything to USENET.

Good luck. It is my belief that most people are unable to learn

Yep, although it depends where your letter is goes to. If it'll
be fed to something like SM/1 or grapeVINE the case conversion and
sorting is necessary.
Now, let's be fair. "Unicode is the standard applicable to writing
letters only", right? Do *you* need such standard?

Neat idea. I'd like to see it implemented, though i don't know
what is the Finnish idea of sorting Chinese.
Even if you have a customized sorting routine, the fall-back
to universal routine is necessary.

Eh? I would think the same way around!
Nope. I propose encoding in which sorting is algorithm (i agree,
the arithmetic sorting is not sufficient).
You can't do it with Unicode/ISO 10646 because you lost
necessary information.
>You are confused about a few things. Unicode will help your sorting

It does not help me with Ukrain and Russian and the fact that
it has the separate cyrillic page is quite irrelevant.

See example before. BTW, Ukrainian has a letter i which is found
in the Latin code page.
>The latter makes no sense if

If you're typing in loan-words you're typing it in the *your* language
(and character codes used belong to your language) and it will be
treated as you wished.

Tell it to the secretary which knows that ls gives sorted list
of files from her directory with couple hundreds of names like
"Letter1" and "IRS_request" in it.

Obviously you don't earn your living by writing programs for
real users. You're underestimating peoples intelligence;
there *are* non-programmers who know a hell lot of shell
and use it.

Thank you for enlightening me, but i wonder if you can tell the
difference between an entire operating system and a single
application -- the localization of those are tasks differing
in compexity for a couple orders of magnitude.
So far, MNOS RL 1.2 and DEMOS 2 are THE ONLY EXISTING true
bilingual systems.

Which Unicode? 16-bit or 32-bit? It already has multiple
codes for similar glyphs but still does not allow algorithmic
sorting or case conversion. What's the point? To combine the
worst of both "one glyph - one code" and my proposal?

>>Aw, don't be silly. It's trivial.
>When you can't explain write off the problem as trivial.
Nope. Simply add conversion CH -> _CH_ to the text editor on
writing the otput file and reverse conversion on reading.
Also, add the same conversion at the copying from raw list
to cooked list in the tty driver.
Isn't it trivial?

It IS issue when you're getting no benefits -- if you have to
specify the language outside of the text you can as well live with
several 8-bit codepages. The onky difference that you needn't
2 bytes for every letter.

You missed the example again completely. The problem was with
the lot of letters like T which AREN'T the same in Russian
and English when converted to lowercase.

ASCII is not a German standard, nor it was designed for German.

If the originator of information does not know which language he

ONLY at input.

I got to like that attitude. "I don't give a damn"...
The user don't give a damn (and a dime, btw) for yor
programs which are unable to do things they have now
for granted.

Non-US ASCII is an oxymoron.

That's ok, but why should i sacrifice things i have now for

I'm in a different business. When i did the internationalization
project i did it quite successfully. You know, a 22 year-old
hippie programmer does not usually get gold medal from the

Thank you for reminding, i do not have amnesia. I do not care

If you don't understand the difference between an example and
proposal you'd better keep out of USENET or bought an asbesto
suit.

KOI-8 is nothin more than a 8-bit ASCII extension with cyrillic
letters in codes from 0300 to 0377. It has completely separate
alphabets for Russian and English even though there is a number
of similar letters.
I used that code only as illustration of model bilingual
encoding.
There were Unicode-style encodings (GOST and DKOI) which
followed the "one-code -- one glyph" principle.
Those encodings are dead by now.
Flame mode off.
