I can report that when using the Unity window manager, the problem goes
away for me -- i.e. with that WM, yzlui window titles show unicode
correctly. The WM I usually use is a bit less feature-packed. I would
be curious to hear whether others have encountered this issue. What WM
are you using, Joshua?
