4.4 National character sets

ANSI/MDC X11.1, Annex A, requires ASCII symbols for codes 0 – 127. Many English language terminals and all other language terminals require different encodings, some of which use codes 128 - 255 as well. Most information systems have addressed the question of printing a symbol on a printer that uses a different code from the keyboard that originated the symbol. Networked systems should also address the translation of codes between agents and servers that use different character sets.

All OMI messages shall use the ISO 8859–1 Latin alphabet No. 1, which equals ASCII for codes 0 – 127, and which specifies common European symbols for codes 128 – 255.

Both agents and servers shall send the standard character set on output and shall accept it as input, except for the following special case:

OMI provides an exemption from this requirement for an agent and a server that share a single non-standard character set internally. When establishing their session they may select untranslated messages, thus avoiding the burden of two reciprocal translations.
