Is there any standard that describes what DEC calls National Replacement Character Sets (NRC sets) ? DEC provides this feature in the VT220 terminal. I have not been able to find an ANSI or ISO standard that contains any reference to NRC sets.

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. Martin Minow decvax!minow
