dear GRASS GIS community,

testing of winGRASS is a important piece of puzzle to guarantee a stable and useable software on the MS windows platform in the future.

For this, we would need the help of the community now. :-)

background is an _error in g.extension while installing i.fusion.hpf in windows_

some more information


it's an encoding issue while opening files via python.

a possible solution may be set PYTHONUTF8=1 as environment variable.

and a way how you could help, just add


in C:\OSGeo4W64\apps\grass\grass79\etc\env.bat just before GRASS_PYTHON is set. (or in the same file in the standalone winGRASS installation).

it would look like:

set GRASS_PYTHON=%OSGEO4W_ROOT%\bin\python3.exe

and then happy GRASS GIS working :-) and report back if there are any issues in your daily winGRASS work.

kind regards
