Decoding gltf file run-time errors in Windows 10

Problem

It fails to decode the assets/models/new/130/scene.gltf and terminate the program due to runtime error.

I have tried a fresh install on both win10 and linux twice, and it works seamlessly with the latter, so I assumed the errors is caused by win10 with the encoding of this specific gltf file.

This error happens occasionally, sometimes the program will be able to finish the whole/half episode.

Is there anyway to load this file in utf-8 or binary mode?

My environment setup

OS: Windows 10 Python version: 3.7 (via Anaconda)

Step to reproduce

python -m pgdrive.examples.enjoy_expert

You can change Windows encoding to UTF8 systemwide. This works for me. 😉

• Maybe panda3d may have support for setting fixed encoding. But I never worked with with it so I don’t know.
• If not, we can as a workaround have the files also have in encoding for windows and load them if windows is detected. But I don’t like this option.

Great! Thanks for you suggestions! Close this issue temporarily.
