Hi Celia,
I ran into this too back when we were transitioning from Python 2 to 3 (2 behaved differently from 3). While researching it I discovered this Python issue which maybe sheds some additional light on the subject: https://github.com/python/cpython/issues/74993

We ultimately found 90 characters that (under Python 3) grew longer when uppercased.

python -c "print([c for c in range(0x80, 0x22ff) if len(chr(c)) != len(chr(c).upper())])”

I hope this is at least interesting. :-)

Cheers
