All of them. IMAP4 protocol **REQUIRES** mUTF-7. UTF-8 is optional in IMAP4, and even UTF-8 capable servers have to support clients without that ability. Check "5.1. Mailbox Naming" in IMAP4 RFC: <http://tools.ietf.org/html/rfc3501>. > Anyway, open an issue ;-) I would like to gauge interest/resistance to the idea from my fellows first. > How is mUTF-7 different than UTF-7? (Why yet another encoding while > standard UTF encodings exist???) As explained in section "5.1.3. Mailbox International Naming Convention": """ The purpose of these modifications is to correct the following problems with UTF-7: 1) UTF-7 uses the "+" character for shifting; this conflicts with the common use of "+" in mailbox names, in particular USENET newsgroup names. 2) UTF-7's encoding is BASE64 which uses the "/" character; this conflicts with the use of "/" as a popular hierarchy delimiter. 3) UTF-7 prohibits the unencoded usage of "\"; this conflicts with the use of "\" as a popular hierarchy delimiter. 4) UTF-7 prohibits the unencoded usage of "~"; this conflicts with the use of "~" in some servers as a home directory indicator. 5) UTF-7 permits multiple alternate forms to represent the same string; in particular, printable US-ASCII characters can be represented in encoded form. """ > Requests of new encodings: I am volunteering and can even do the mercurial PUSH myself :-p. That is an advantage over some of those new encoding requests :-pp. But then yes, I realize that this is a specialized tool (even if IMAP4 is probably the most popular mail access protocol in the world), we can accommodate every use-case and there are tons of mUTF-7 libraries out there already.
