ISO 6937 is certainly not supported in X.400-1984. But nothing forbids you
to write a translator between this alphabet and the TELETEX alphabet T.61,
which is almost a superset of ASCII, and can express all the various form of
accentuated letters in 6937 -- plus some more, just to please the Malteses
and the Romanians..

T.61 is ``almost'' a superset for the status of the nationally definable
code positions of IA5 is very unclear. It seems to be forbidden to use them
in the plain CCITT T.61, which forbids the encoding of e.g. braces. There is
an ISO equivalent of T.61, where these characters are defined -- and shall
map to the ``international IA5'', i.e. American...
