Gaim 0.59.3 should work more or less properly for the UTF-8 protocols
(as you say, MSN) if you have your locale set correctly. I use it
regularly to converse in Japanese, which is much more difficult to
convert than, say, KOI8-R.
As far as ICQ and AIM, we haven't quite made it that far, yet. :-)
I haven't looked at rusconv, but I suspect it is either using an
application-specific encoding (in which case we're basically lucky
it works) or abusing the Unicode encoding as a pure 8-bit transport
(in which case we're even more lucky it works). The right answer is
to convert Oscar packets to UTF-16, and that is being worked on...

The plan is to move CVS over to using UTF-8 exclusively internally.
Basically, by the time a string leaves the protocol plugin, it should
be converted to UTF-8. For the UTF-8 protocols (MSN, Jabber, we think
Yahoo!), this is trivial. For Oscar it is less trivial due to some
design flaws, but it is not horribly difficult.
The "local client" encoding you mention is no longer necessary with
Gtk2, or will not be once everything is ported over to pango-using
widgets. The reason for this is that the "local encoding" as far as a
Gtk2 appliction is concerned is always UTF-8.
Logging presents a slight problem here, my gut instinct is that
logging should honor LC_CTYPE ... however, since logging is currently
done through gtkimhtml (which will be going all UTF-8) as best I can
tell, this may require some work.

The correct answer for ICQ is to just use the Oscar Unicode transport
settings. Like I said, it's being worked on. :-) (Where "worked on"
is a nebulous concept lately...)

I've committed to helping make gaim perfect in the i18n department.
:-) Just as soon as I have some free time to kick around, hopefully
we'll start seeing real improvements in that area. As Luke said, the
move to Gtk2/Pango is certainly going to help.
Thanks for your comments, and stick around for the changeover... I'll
need plenty of bug-testers. :-)
