Certain Characters in Passwords Cause Authentication Error in GIT Client

[Skinnix]

Similar to #704, when you have a German umlaut (in this case "ä") in your password, you can log into the web interface but authentication in the GIT client fails (tested with Tortoise and Sourcetree). Removing the Umlaut fixed the issue but this may not always be an option.

The error occurred when using Windows authentication.

Here are some possible solutions or workarounds:

1. Change the Encoding in the GIT Client
   Ensure that the GIT client is using the correct character encoding, typically UTF-8, which can handle umlauts and other special characters. Some clients allow you to configure this in the settings.
2. Use an Access Token Instead of Password
   If your GIT hosting service supports it (e.g., GitHub, GitLab, Bitbucket), you could generate a personal access token and use that instead of your password. This bypasses the issue of character encoding in passwords.
3. Escape the Umlaut
   In some cases, encoding the umlaut character using percent encoding (for example, "ä" as %C3%A4) might resolve the issue. However, this depends on whether the client allows you to enter percent-encoded characters in the password field.
4. Ensure Consistent Locale Settings
   Verify that the locale settings on your system are consistent across all applications. If your system locale or keyboard settings differ between the web browser and the GIT clients, it could cause issues with how special characters are interpreted.
5. Update GIT Clients
   Ensure that both Tortoise and Sourcetree are updated to the latest versions, as newer releases may have fixed issues related to character encoding in authentication processes.
6. Check for Known Issues
   Look through the bug trackers or forums of the GIT client software (Tortoise, Sourcetree) to see if this issue has been reported and if there are any patches or fixes available.
