• Unity editor version: 2020.3.19f1
• Firebase Unity SDK version: 8.6.2
• Source you installed the SDK: .unitypackage
• Problematic Firebase Component: App

When running as a standalone executable, Firebase is unable to create app/load Firebase app options when a non-ASCII character is present in the directory name/path.

Here is a YouTube video demonstrating this bug:

This appears similar to firebase/quickstart-unity#1089 firebase/quickstart-unity#1069 firebase/firebase-unity-sdk#427

Steps to reproduce:

To reproduce the issue:

1. Create new Unity project
2. Import Firebase Unity SDK
3. Create a method/function which tries to login with Firebase Auth, and a way to call that method/function.
4. Build a standalone executable 4a. Assuming the build is in a folder that does not contain any special characters, the login attempt should succeed at this point
5. Rename the directory where the build is located to something which contains a special character
6. Attempt to login and the following error will be thrown:

InitializationException:  Firebase app creation failed.

This has been fixed in the Firebase C++ SDK,, and the fix will be included in the next release (11.3.0) of the Firebase Unity SDK. Closing this bug, but feel free to reopen if it recurs in the future.
