[GRASS-dev] Trunk breakage with Python 2

Fri Apr 26 12:29:20 PDT 2019

Hello everyone,
is Python 2 still supported or trunk is already 3 only? If it is
supported, then a serious fixing is required. If it is Python 3 only,
then it should run on Python 3 and not 2.

After recent changes, most of GUI functionality is more-less broken
with console filling with various UnicodeDecodeError errors. Startup
screen works (sort of), autogenerated GUIs – only partial
functionality, layer manager & map window – fail to start.

python --version
Python 2.7.15
