Unicode characters in ENvironment Variables make the pharo-launcher #620

Open adrian-castravete opened 1 year ago

adrian-castravete commented 1 year ago

Describe the bug Having Unicode characters in any of the environment variables makes the pharo launcher break while Clicking "Show" in the VMs and probably hangs while trying to launch an image.

To Reproduce Steps to reproduce the behavior:

  1. Go to the location where you installed the Pharo Launcher
  2. Click on the launcher file (pharo-launcher)
  3. Update the virtual machines
  4. See error WideString does not understand #tfPointerAddress with a Debug button and an Ignore one.

Expected behavior The Image should open.

Screenshots Error Window: screenshot

Clicking debug I got a hint of the problem: screenshot2

Version information:

Expected development cost I don't really have a good idea. I know about Smalltalk from a long time ago, but I'm at maximum a hobbyist. I have no idea exactly how to fix things. My skills extend to small debugging.

Additional context So as I mentioned and is showed in the screenshots the problem is having

XDG_DOWNLOAD_DIR=/home/fkbm/Descărcări

in the environment. Launching the pharo-launcher with:

XDG_DOWNLOAD_DIR=/home/fkbm/Test/Downloads ./pharo-launcher

A similar error occurs because I also have:

XDG_MUSIC_DIR=/home/fkbm/Muzică

Now relaunching with:

XDG_DOWNLOAD_DIR=/home/fkbm/Test/Downloads XDG_MUSIC_DIR=/home/fkbm/Test/Music ./pharo-launcher

fixes everything, but it's not a normal/nice way of fixing it.

Anyway, for the error showed in the screenshots the debug log is:
