Unicode Input

[tidhar.mor]

Hi,

I'm using GTV on Logitech Revue in Israel and I was wondering if anyone knows if it's possible to enter text in Unicode (in order to use Hebrew).
I tried using the GTV remote app on my phone and switching to a Hebrew keyboard, but when I type nothing shows in the search box on screen.
Hebrew fonts show with no problem in the browser and in apps (as folder names or file names for example).

Hope somebody can help,
Tidhar
