Anyone out there got a description of any character sets and collating
sequences that include all the roman characters and accented roman
characters?

Someone was telling me about ISO stuff and how there were a whole load of
8-bit sets that define most of the european characters.  That would be kind
of useful, but what I really want is a full description of either a 16-bit or
32-bit character sequences that will include all the roman chars and their
accented chars in a sequence that I can sort on.

I guess someone has a PostScript file or something?

Thanks

Keep in mind that sorting methods are locale/implementation-dependent.
For example, an English-based sorting system will put Angstrom (with an
A-ring) before Zyzzyva, but a Swedish-based sorting system will put them
in the opposite order (since A-ring comes after Z).  To give a slightly
trickier example, a Spanish-based sorting system will put "llama" after
"LZH," because "ll" is a separate letter which comes between "l" and "m."

I am not sure if anybody really knows how many roman letters and
accented letters there exist, but a fair part have been tabled and
sorted in some POSIX compliant locales available at dkuug.dk in
the directory i18n. The locales also include specification of
greek and Cyrillic and Kana sorting.

As noted in another article the sorting sequences are different for
at least some languages. The locales available at Dkuug.dk covers 

                        da_DK                 Danish
                        en_DK                 English

The English one is actually intended to be quite general, also
covering languages as German, French, Italian, Portuguese, Dutch,
Vietnamese, Greek, Russian and Japanese

There are also provided POSIX charmaps for ISO 10646 - only a part tho,
something like 2000 characters. And about 100 other character sets
like the ISO 8859 series, PC codepages, EBCDICs are also described
via POSIX charmaps.
