There are various different algorithms to lowercase non-ASCII characters. Dovecot even has some code to do it if libicu is compiled in. Still, I'm not planning changing %L behavior anytime soon. Non-ASCII usernames don't work especially well now and I don't even want to try to support them well right now. That would require bigger design changes.
