Terminal Special Chars Follow

Hi,

I recently started using IntelliJ IDEA Ultimate on Windows 10 and would really like to use the integrated terminal.
However, I can't get it to work with special characters like german umlauts or something like §.

That wouldn't be a problem if i hadn't some folders starting with Ü which i can't rename because they are part of a version control repo.
Because of that, i can't cd into these folders.

For example, an "ü" keystroke shows as "3R" and a "§" keystroke shows as "?" (like most special chars).

It neither works with the default terminal setting (cmd.exe) nor with git bash.

Has someone encountered a similar problem?
