Unicode input does not work

```
What steps will reproduce the problem?
1. Connect to VNC server (tightvnc running on winxpsp3)
2. Set focus to any input control on the remote server desktop and enter some
non-ASCII characters - this could be done either by selecting another input
language or via long tap on any vowel and then selecting a diacritic character
from the popup. Example text: résumé, àáâãçéêíóôõúфжмыъ

What is the expected output?
Non-ascii characters are sent over to the server and appear in the input
control on the target desktop system.

What do you see instead?
All non-ascii characters are ignored. Only plain ascii is accepted.
