That would certainly work for the interface between the MIT library
and the calling application.

I think the challenge will be credential caches,
keytabs, replay caches, etc.  Those are resources which are shared with
other Kerberos implementations that will not necessarily be happy if the
character sets changes.

I can see the possibility of issues where tickets for the same service
get stored under two different names, or keytab entries that cannot be
found, or replays that are permitted between applications which use
different character sets.
