Apparently, this has something to do with domain controllers
(see http://support.microsoft.com/kb/291010, for example). They need the
GUID subject alternative name hex-encoded.

Hmmm, is this really needed? I believe that before serialization, the
necessary data should be encoded to UTF8 using encode_utf8($string)
and decoded afterwards using decode_utf8($string) ... Thus, for the
serialization it is just binary data, for which the user has to decide
whether he assumes that it is UTF8 or not.
Your approach would shift the user decision to whether the perl UTF8
flag is set or not, I'm not sure if this is exactly what we want ...
Not sure if this makes perfect sense, I still don't really grok the
Perl Unicode handling, maybe someone can clear that up a bit more ...
Best regards,
Alex
