The XMPP RFC 3920 says that the node portion of a JID (the part before
the @ symbol) should be mapped using STRINGPREP tables B.1 and B.2.
Loosely translated, that means that the node is supposed to be
case-insensitive.  Since gaim can safely ignore case, it normalizes them
to lowercase, so that a standard strcmp() can be used in the core, and
not have to bother the prpl about particulars.

Sony's servers are definitely off-spec if they're treating the room
names case-sensitively.  Unfortunately, there's not much I can do to fix
your problem without serious structural changes in gaim core that aren't
going to happen any time soon.

As to your patch, if that actually works, I'm impressed.  What you meant
to do (which will still brain gaim's jabber support, should the other
side decide to send things with 2 different cases), is replate
g_utf8_strdown() with g_strdup();  But don't do that, it breaks things.


You can file a bug if you want, but it won't get much attention any time
soon.
