| O/R addresses in X.400 (1988 and later, which includes MAILbus 400) systems use
the Teletex character set. This is a single 8-bit set which supports just about
every character in the ISO Latin-n sets. It basically works the same as the
Latin sets, using the system of designating/invoking character set repertoires.
It's just that the default repertoires include non-spacing accents and
diacritical marks which allow you to construct a wide range of characters.
Hence you can use ISO Latin-2 today without any difficulties for transferring
information around an X.400 network.
Your problems arise, however, with getting the data into and out of X.400.
Most, if not all, end systems don't use Teletex, they use one of the ISO Latin
character sets. The MTA's management module na�vely assumes that you will
always be using a Latin-1 terminal to input data to the MTA, and so interprets
byte values according to the Latin-1 character set for converting to Teletex.
ALL-IN-1, the largest DIGITAL-produced user agent for MAILbus 400, does have
configurable character set tables, for mapping between Teletex and the
appropriate local character set. However, the base product ships with only the
Latin-1 tables, and as the product is not translated into any languages that use
Latin-2, the extra tables are not available, either from engineering or the
localisation centre. Also, they are not site customisable.
But depending on what products you're trying to use, and what you are trying to
achieve, there are a few tricks you can do to get Latin-2 values into the system
(in their Teletex-encoded forms). If you can explain what you want to do, I'll
try and explain how you can do it.
