This commit lead to a regression when using Meson on Windows to build the Mesa project:

The reason is that pathlib.read_text now uses the locale as the encoding when reading files when there's no encoding explicitly passed in. That means that C++ source files are attempted read as CP1252 on Windows, which throws exceptions when source files contain UTF-8 code-points.

After digging some more, I no longer suspect that this commit is to blame, but instead some logic in Meson that effectively disabled the problematic code under in our use-case before we upgraded our Visual Studio version.

The reason is that I was able to reproduce this using Python 3.9, and as far as I can tell that doesn't contain this change.

So, sorry for the noise. I'll close this, and rather reopen if I find out I'm wrong.
