Theme can not be applied

[borish43b]

I am not able to change the theme.

Steps:

1. Select "Edit -> Preferences..."
2. Change "Theme" in the "General::General" section
3. Click "Apply" or "OK"

Expected behavior: The theme is changes to the selected one

Observed behavior: The following error is yielded: boost::filesystem::create_directories: Zugriff verweigert [system:5]: "C:\Users\[[USERNAME]]\AppData\Roaming\FreeCAD\SavedPreferencePacks\Backups", "C:\Users\[[USERNAME]]\AppData\Roaming\FreeCAD" The theme is NOT applied.

Additions:

• The selected theme and all other settings are persisted. If I close and restart FreeCAD, the selected theme is shown in the preferences. The theme is not applied, however.
• All other settings (e.g. language) take effect and are persisted as expected.
• [[USERNAME]] contains a "german umlaut" letter (ä). There has been some issues with this in the past, already. Maybe this causes the issue.

This is definitely an issue with the character encoding in the path (again, there had been an issues with this for the plugins a few versions back). I have created a new user “Tester” and everything worked fine. Then I have created another user “Täster” and I got the exception again.

Also applies to the newest build.
