Hmm. Then either maildirinfo.c or the man page is not correct. "man
maildir" says:

If I'm not mistaken this tells me that '.' and '/' may be used, but
must be encoded and '~' and ':' aren't considered anything special.
Btw: What about the backslash '\'? If anybody is crazy enough to use
Windows for a mail server, this character definitly poses a problem
(together with ':').
I just checked - Unicode::IMAPUtf7 also encodes '~', '\' and '+', but
'+' becomes (incorrectly) '&-' which is the encoded form of '&'. It
doen't bother with '.', '/' or ':'.
Then I found Encode::IMAPUTF7, which leaves all theses cheacters
('./+\:~') unencoded.
Both modules don't quite do what the "maildir" page demands. :/
Regards,
Norbert
