[Message part 1 (text/plain, inline)]
Package: x2goclient
Version: 4.1.1.1
Tag: patch

If the session name is written in Cyrillic (I guess, any Unicode), the 
window title is displayed incorrectly (as if Unicode was not understood, 
with strange symbols) in the task bar in the KDE panel.

See the attached screenshot (made by mcpain@).

Patch (by mcpain@ and zerg@) is attached, too: 
x2goclient-4.1.1.1-window-title-encoding.patch

The client and server OS are: ALT Linux (Sisyphus or p8).
The window manager is KDE.
