Umlauts in Path -> GDX Open broken #134

Closed universal closed 6 years ago

universal commented 6 years ago

On trying to open a GDX file, where the parent directory contains an umlaut results in the following error:

Unable to open GDX file: /home/XXX/development/repositories/GAMS/XXXIntensitätsstufen_Düngeraufkommen_XXX/tmp/3aggregate.gdx
Error: Ungültiges oder unvollständiges Multi-Byte- oder Wide-Zeichen

Symlinking the directory to a path without an umlaut, the gdx file can be opened and viewed just fine.

Environment: Ubuntu 18.04, GAMS - 25.1.1, ntfs formatted drive

On an unrelated side note: This reminded me: Whenever i try to run gams from the command line and the path contains a space, gams does not want to execute the file :( And I've to symlink the directory, from where it works just fine...

The umlaut issue occurs on all platforms (Linux, macOS, Windows) and on macOS/Windows umlauts are also not correctly displayed in the output log.

Currently this is a legacy of GAMS on Linux and macOS. If GAMS is used on Windows spaces in paths should just work fine.

The umlaut issue has been fixed, which will be part of the upcoming GAMS Studio 0.9.3.

For the path with spaces a new ticket has been created (#166).
