glTF Exporter: Non-ASCII characters corrupted in exported data

[yushimatenjin]

Description

Hello,

I've encountered an issue while using the PlayCanvas glTF Exporter.
It appears that the exporter is not functioning correctly when entity names, materials, or textures contain non-ASCII characters.

Version

• PlayCanvas Engine v2.1.0

Steps to Reproduce

1. Here are the sample project and execution URLs:

• Project URL: https://playcanvas.com/editor/project/1265143
• Execution URL: https://playcanv.as/p/4xbkD82g/

2. Attempt to export the models using the glTF Exporter:
   a. Model with English-only content
   b. Model with Japanese characters in entity/material/texture names
   c. Model with emoji in the entity name
3. Try to load the exported models in PlayCanvas Viewer and Blender

Result

1. English Only

• Entity name + texture + material name are in English.

• This worked normally, and I could load it without issues in both the PlayCanvas Viewer and Blender.

2. Containing Japanese characters

• Entity name + texture + material name are in Japanese.

• The model can be viewed in the PlayCanvas Viewer but entity names appear corrupted, indicating that the export wasn't successful
• I couldn't import the exported model data into Blender

3. Containing emojis

• Entity name includes an emoji.

• This model couldn't be loaded even in the PlayCanvas model viewer.

Has anyone else experienced this problem or know of a workaround? Any assistance would be greatly appreciated.

Thank you for your help.
