There used to be partial support for EBCIDC in GnuPG (e.g. a
table to define what characters make up a word), but this was dropped
some time ago when GNU/Linux was ported to run on VS.
However there are more things to take into account, for example you
will find isascii() tests at some places and the code _might_ now
assume to run on an ascii system. That said, it won't be sufficient
to add just a new character conversion to get a full interoperable
application. OTOH, GnuPG is written as a POSIX program and should be
portable to all POSIX platforms; it is just that non-ascii systems are
not on very desktop or server nowadays ;-)

You need to change util/strgutil.c, utf8_to_native and native_to_utf8,
the current implementation assumes ascii in the low 7 bits. If you
need help please feel free to ask me at firstname.lastname@example.org.
