[Bug] "Unable to load Firebase app options" when running as standalone executable in a folder which contains non-ASCII characters

[jiahengnz]

[REQUIRED] Please fill in the following fields:

• Unity editor version: 2020.3.19f1
• Firebase Unity SDK version: 8.6.2
• Source you installed the SDK: .unitypackage
• Problematic Firebase Component: App
• Other Firebase Components in use: Auth
• Additional SDKs you are using: None
• Platform you are using the Unity editor on: Windows
• Platform you are targeting: Desktop
• Scripting Runtime: Mono

[REQUIRED] Please describe the issue here:

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:

Hi @jiahengnz,

Thanks for reporting this issue. Could you provide the sample code you used so that we can identify what's causing this behavior? Could you also confirm if the error message also appears in the Unity editor?

[jiahengnz]

Hi,

The error message does appear in the editor after renaming the project folder to FirebaseMinimalTést.

Source code attached below.

Run in editor/make a build as it is and it will login fine. Change the project name or build folder name to, say, FirebaseMinimalTést, and it will throw the error

Hi @jiahengnz,

I've downloaded the sample project you provided, but I wasn't able to replicate your issue. However, I should point out that I'm using version 2021.2.3f1 of the Unity editor. Could you try using an updated editor and see if the issue persists?

[jiahengnz]

Hi,

Just tested in 2021.2.4f1, the bug occurs in both the editor and the build. Have you renamed the project folder to one with a character like é? The zip as it is will run with no problems.

Hi @jiahengnz,

It turns out I didn't encounter this issue at first because I was using a macOS device. I recently tested this on a Windows machine, and I was able to encounter the same error message.

I'll be marking this as a bug for now. Let me discuss this with the team, and I'll get back to you once I have updates.

[jiahengnz]

Excellent, I look forward to hearing back from you

[yubingxdc]

is this issue resolved now? I am still encountering same issue.

[robojiannis]

hey @paulinon any news on this one? We're encountering exactly the same issue as described, using version 11.1.0

[jonsimantov]

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.
