Re: [STUMP] UTF8 related bug

[Vladimir Sedach]

Also, and important: signal handlers need to be added to stumpwm to
prevent encoding errors from crashing the whole window manager. This
means some thing will not work if stumpwm assumes UTF-8 encoding and
the filenames or X give back Latin-1 or similar, but it's better than
dying.
