UTF-8 keyboard?

[Shachar Shemesh]

Hi all,

A while back someone (I think it was Alexander) mentioned something 
about UTF-8 working for keyboard detection and entering info. That same 
mistyrious someone said it was in XOO, and will be merged when Alexander 
finishes his merges.

I just tried it with latest CVS, and I am getting mixed results. If I'm 
using an unknown encoding, when I run wine with +keyboard, I get:

When I run it with en_US.UTF-8, I get:

That is - no errors, but I don't get any characters on screen either.

When running this with locale he_IL, I get this:

Characters do appear on screen, this time. Could it just be that edit 
control (I'm using notepad to test this) does not support UTF-8?
