I cant really give comprehensive answers here since I just got this
working on a basic ghost-x11/python/event level,
and made sure switching to foreign keyboard layouts resulted in
foreign looking keys.

The same issue shows up on X11, though I think its todo with the font,
at least if you use the mono-space font it works
Run this in the console and render to see.
bpy.context.scene.render.stamp_note_text = '\u00DC'
bpy.context.scene.render.use_stamp_note = True
bpy.context.scene.render.use_stamp = True
On a related note, to render latin1 characters I had to add an
exceptions to glib's utf8 function, since it would have otherwise
returned an invalid char.
I did this mainly because paths can have non utf8 characters and the
code we had in BLF from ImLib also happened to work this way though it
didnt make a special exception.
Guessing this is a freetype/font issue (or some setting we miss) since
we pass the unicode chars to freetype without any changes.

There has been no attempt to get this working, we have the python
console too, I was hoping to have text button input first.
for basic text entry and line editing its not too hard, but fore line
wrapping, tab spacing etc... this could be quite a bit more work
(could be worth looking into a blf/scintilla port instead)
