Thx.

 

Hello, I encountered the same issue, but I don't understand what you mean "by encoding Unicode characters in the jslib".

Could you please give more details about that?

BTW the link to the issue says I don't have permission to access this portal.

Thanks.

 

did you solve this problem, I encountered the same issue

 

Not yet, even not having a clue at all.

 

I delete all jslib file's unicode characters, it's ok

 

Thanks so much!
I'll have it a try.

 

Thank you!
It works well!

 

I suddenly started getting there, where are the jslib files that need to be tweaked? im using 2022.1.16 - is it worth upgrading to see if its fixed?

 

if you are really stuck like I have been, turned out to be this asset https://assetstore.unity.com/packages/tools/audio/webgl-speech-105831#description

 

I found a workaround. Put this code as editor script.

using System;

using UnityEditor.Build;

using UnityEditor.Build.Reporting;



public class WebGLEmscriptenBuildFixer : IPreprocessBuildWithReport

{

    public int callbackOrder => 1;

    public void OnPreprocessBuild(BuildReport report)

    {

        Environment.SetEnvironmentVariable("PYTHONUTF8", "1");

    }

}

This code will set env var PYTHONUTF8=1 so that it enforces python (emcc.py) to use UTF-8 encoding. So the UnicodeDecodeError will not occur.
