Yeah, GTK+ 2 is slower, but the culprit is not necessarily UTF-8. GTK2
is generally better thought out, and that sometimes means "Doesn't do
moronic stuff which also happened to be fast".

It should also be noted that when many apps ported to GTK2 they
performed a whole hog rewrite of the codebase (the switch in Gaim, for
example) which may also be the cause of the problem.
