Program seems to be fine at start but when some of That character appear in the TextCtrl the EVT_TEXT which call function OnTextChange just stop working, all thing back to work properly again when all those character removed.
After hours of debugging and searching for information about unicode bug in wxWindows, I noticed that there’s python exception in SPE’s shell. This bug is nothing but SPE’s coding without aware of non-latin chracter.
I’m going to happily sleep now.</event_handler>
