Okay, I see your problem now, the terminal emulator _may_ replace the
presented chars with equivalents in the font. But it's hell of work if
done right, it has to check every char, locate most similar character
in some encodings map and replace it. I expect xterm to become slower
and more memory consuming if this will ever be implemented. However, why
do you not just set the locale to Latin1 if your X-Terminal/X-Server
does not support Unicode fonts?

I think you mean libpango and not Gtk2. Many Gnome applications use
libpango.

As said, this would make them slower. Setting the locale to the one best
supported by the X-Server is easier.
