The standardisation of character sets is a combined effort of ISO
(the international standards organisation), ECMA (the European
computer manifacturers) and CCITT (the international telephone and
telegraph association).  Through ISO participated the national
standards institutes like ANSI.

Either ANSI X3.41 or the associated ISO standard defines the
sequences to designate alternate character sets (I do not know
which from memory; but probably both):

DG0	ESC ( s		Designate G0 to G3
DG1	ESC ) s		s is from the table below.
DG2	ESC * s
DG3	ESC + s

XDG0	ESC , s		Designate G0 to G3
XDG1	ESC - s		s is not yet standardised.
XDG2	ESC . s
XDG3	ESC ? s

MBC	ESC $ s		Designate multibyte character set.

Character sets are put in a registry by AFNOR (the french standardisation
institute) on behalf of ISO.

As of 1977 the following character sets were registered:

Symbol	Organisation	Year	Use

@	ISO		1975	Reference version
A	BSI		1975	British use
B	ANSI		1975	ASCII
C	NATS		1975	Swedish/Finnish for newspaper use
D	NATS		1975	Additional symbols to C
E	NATS		1975	Danish/Norwegian for newspaper use
F	NATS		1975	Additional symbols to E
G	SIS		1975	Swedish use
H	SIS		1975	Swedish use for names
I	JISC		1975	Katakana
J	JISC		1975	Latin set for Japanese use
K	DIN		1975	German use
L	ECMA		1977	Portugese use
R	AFNOR		1975	French use
U	ECMA		1976	Mixed latin greek (also LC latin)
V	ISO		????	additional for bibliographic use (draft)
W	ISO		????	Cyrillic for bibliographic use (draft)
X	ISO		1976	Greek for bibliographic use
Y	ECMA		1976	Italian use
Z	ECMA		1976	Spanish use
[	ECMA		1976	Greek use
\	ECMA		1976	Mixed latin greek (UC only)

Organisations:
AFNOR	French standards institute
ANSI	American National Standards Institute
BSI	British Standards Institute
DIN	German standards institute
ECMA	European Computer Manifacturers Association
ISO	International Standards Organisation
JISC	Japanese Industrial Standards Committee
NATS	Scandinavian Newspaper Technical Cooperation Council
SIS	Swedish standards institute

This list is not complete of course (it is 8 years old); missing is
for example the multibyte japanese kanji character set.
Any additional information to this list is welcome.

Also missing is RUSCII (eh GOST 13052), the russian cyrillic character
set.
For those interested in its encoding, send me mail and I will send it
back.
