Problem with Python 3.10 and python-wxpython4 in Rawhide

[Steven A. Falco]

I have python3-wxpython4 4.0.7-19.fc35 and python3 3.10.0~b4-3.fc35 on a rawhide VM.  I
get the following error:

rawhide$ python -c "import wx;print(wx.version())"
Traceback (most recent call last):
   File "<string>", line 1, in <module>
   File "/usr/lib64/python3.10/site-packages/wx/__init__.py", line 17, in
<module>
     from wx.core import *
   File "/usr/lib64/python3.10/site-packages/wx/core.py", line 12, in
<module>
     from ._core import *
UnicodeDecodeError: 'utf-8' codec can't decode byte 0xc3 in position 261:
invalid continuation byte
free(): invalid size
Aborted (core dumped)

Should I file a bug on Fedora, or should it go upstream, and if so, where?

	Thanks,
	Steve

Yeah, I'll try to look into it later today.

In case anyone was curious, this turned out to be a sip 6 issue rather 
than anything to do with Python 3.10.  sip 6 seems to have issues with 
non-ASCII characters in Python docstrings.

Thanks for the fix, Scott.  That let me close the FTBFS on KiCAD.

Just curious - will this fix be forwarded to an upstream, or is this a problem unique to
Fedora?

From a wxPython perspective, it's unique to Fedora in that upstream 
wxPython uses sip 5 officially, whereas Fedora has moved to sip 6.  (I'm 
not sure about that wxPython GitHub issue you found where someone had 
previously reported a similar problem - not enough details from the OP.)

I did report the problem to sip upstream, as that's where the root issue 
lies, as far as I can see - no response as of yet.
