[Octave-bug-tracker] [bug #58689] [MXE Octave] Update mesa to use meson as (native) build tool

[Markus Mützel]

Follow-up Comment #3, bug #58689 (project octave):

Thank you very much for your help.

I applied your patch on top of hg id e60d29a560ab and tried to test by
building for Windows including binary packages.
The compilation failed at of-tsa with the following error in the build log:

This is probably because the file sinvest2.m is encoded in Latin1 and contains
the character "²" (superscript 2).

Should that be considered a bug in of-tsa (wrong encoding, should use UTF-8)?
Or should we change the script pkg-install.py to take whatever encoding it is
fed?
