Actually, this should be the exact text Emacs received from
the gtk2 application, thus it seems that gtk2 has a bug in
producing COMPOUND_TEXT.

Perhaps, that because the other apps use UTF8_STRING request
on selection (which is XFree86 extention) but Emacs 21.3
uses only COMPOUND_TEXT request (standard of X).  The latest
CVS version of Emacs supports UTF8_STRING.

???  Then, in what locale were you running gtk2 apps when
pasting didn't work?

I'm sure this is not related to input method.

Emacs never generates such \x{.....} notation automatically.
So, the text should be generated on sender site.
