with source file in UTF-8 you have full UNICODE support

[Erhy]

Hello!
This is only a message for my solved problem to get UNICODE support.

With Windows I code for Python 3.7 with the tool PythonWin which comes with the package pywin32

I had the problem with strings having characters of the upper area of latin-1 upper range .e.g. ß

After hours I had the idea to
convert the python script file to UTF-8 with Windows Notepad.

Suddenly with the so converted source file (encoded in UTF-8)
I had full UNICODE support.

Hope this helps other

Python 3 has full Unicode support built in, I'm not sure I understand the original problem, nor the solution.

Your editor 'PythonWin' should save it as utf-8
