I am a bit reluctant at this time to assume that untyped data coming in
that looks like UTF-8, really is UTF-8. Even if the LDAP lookup returns
plausibly useful results, will the UTF-8 envelope survive related
processing in Postfix?
- PCRE lookups don't currently request UTF-8 support
- Logs don't support non-destructive recording of UTF-8
envelopes.
- What is the character-set of mailbox content?
- What character set should pipe(8) commands expect?
So I think we are quite far from really supporting UTF-8, and issues
deeper than LDAP table support probably need to be handled first.
