In verbose mode, if files differ in share_files(), dhpython will try to show a diff of the files. When these files are static libraries, this raises a UnicodeDecodeError. For example, from a recent numpy build on arm64[1]:
W: dh_python3 fs:146: Paths differ: debian/python3-numpy/usr/lib/python3.10/dist-packages/numpy/random/lib/libnpyrandom.a and debian/python3-numpy/usr/lib/python3/dist-packages/numpy/random/lib/libnpyrandom.a

There is already logic to skip this diff for .so files, so the same should be done for .a files.

This bug was fixed in the package dh-python - 5.20220923
---------------
dh-python (5.20220923) unstable; urgency=medium
[ Stefano Rivera ]
* Run Python test suite with nose2. (closes: 1018338)
* Don't attempt to diff static libs (.a), thanks Nick Rosbrook.
(closes: 1020528)
[ Debian Janitor ]
* Bump debhelper from old 12 to 13.
+ Drop check for DEB_BUILD_OPTIONS containing "nocheck", since debhelper now
does this.
* Remove constraints unnecessary since buster (oldstable):
+ dh-python: Drop versioned constraint on python3 in Replaces.
[ Stuart Prescott ]
* pyproject plugin: Make the package's entry points available in the PATH
when running the package's test suite, so that tests using the entry
points can be run.
