command line and special chars lead to error
Executing a geo script in batch mode does not work if the path of the geo script contains special chars such as the German "ß". Same with many other UTF-8 chars. Below an example.
gmsh.exe "C:/test-üßµ/test.geo" -o "C:/test-üßµ/test.inp" -save -format inp
I'm on Windows 10.
If you want to reproduce the issue, simply place any geo script in a path that contains "ß" and run it from the command line as in the example above.
The errror is both at reading the geo file as well at writing the mesh to the inp file:
Error : Unable to open file
