Help testing Exchange IMAP server search?

[Eric Abrahamsen <eric@ericabrahamsen.net>]

Hey can someone(s) with an IMAP account on a Microsoft Exchange server,
who is running Emacs from master, help me test search capability?

I just pushed a change to gnus-search that will help improve search
handling for Exchange servers, but there's more work to do.

In a nutshell: Exchange advertises the LITERAL+ capability. But it only
accepts searches using the US-ASCII charset. Right now, if the code sees
a non-ascii search string, and the server has LITERAL+, it will encode
the string using the literal+ format and send CHARSET UTF-8, which
results in an error from Exchange.

The other option is to ignore Exchange's LITERAL+ capability, and put
double quotes around the non-ascii string. I don't know if that will
work or not, that's what I need help testing.

I'm hoping someone will:

1. Pull and build today's Emacs code.
2. Search an ascii-only string like "FROM eric" (it doesn't matter if
   you use the parsed queries or not) and verify it works.
3. Search a non-ascii string like "FROM Jérôme" (something that *should*
   return results!) and tell me what happens.
4. Eval the method definition below, and repeat both of the above tests.

Thanks in advance!

Eric
