Subject: [PATCH] Bugfix #1676

Ancient bug: texteditor input was limited to "isprint()" characters, the
default non-accented simple ascii set. I've removed that.

Now we still have a conflict with hotkey handling, so ALT+character input
won't work. But, for keyboards that have special character keys from itself,
this patch will allow typing them in Text now.
