fix: punktum app module fails to import on Python 3

[serrebidev]

Problem

addon/appModules/punktum.py is encoded in cp1252 and has German umlauts in its first-line comment, but declares no PEP 263 encoding line. Python 3 assumes UTF-8 when no declaration is present, so the file fails to parse and the Punktum app module never loads:

SyntaxError: Non-UTF-8 code starting with '\xfc' on line 1, but no encoding declared;
see https://peps.python.org/pep-0263/ for details

The offending line is the comment itself:

# Unterst<FC>tzung f<FC>r "Punktum"

It shows up as ISO-8859 text rather than UTF-8, and it is the only module in the add-on in that state — every other file is already UTF-8.

Fix

Re-encode the file as UTF-8. Only the two umlaut bytes change (0xFC becomes 0xC3 0xBC); no code is touched, and no encoding declaration is needed since UTF-8 is the Python 3 default.

Verified with python -m py_compile, which fails before the change and succeeds after.

Closing as a duplicate — the punktum UTF-8 re-encode is already covered by #7 and #8, which I missed before opening this.

Note for whichever gets merged: the stray trailing dot on import appModuleHandler. that #7 also fixes appears to be gone from main already, so on current main the encoding is the only remaining problem in that file.

Sorry for the noise.
