Page 2-1 and 2-2 of the VT220 programmer reference manual contain
a list of seven Ansi and ISO standards.  I believe you might
want to start with ISO 2022 and 6429 (but I'm not certain if
they have what you want).

In general, National Replacement Character Sets are standardized
by a National Standards Institute (such as ANSI in the USA) and
registered by that body with ISO and/or ECMA (European Computer
Manufacturers Association).  ISO (I think) assigns intermediate
and final escape sequence characters that are used to select
that character set.  This is described in Chapter 4 of the
VT220 manual.

The thing we all call "Ascii" is really the United States
National Replacement Character Set.
