Better test how your user interface behaves when a user copy-pastes one of those characters into it. If it merely garbles the character somehow, you may be able to ignore the problem, but if it promptly shuts down your whole application and loses some unfinished work, the user may not be happy. Klingon may not be that widely spoken, but all manner of little picture characters seem popular. Wasn't one just chosen to be the Word Of The Year? And when it's the underlying GUI library that crashes, it's too late for your program to sanitize the input. -- https://mail.python.org/mailman/listinfo/python-list
