TextMeshPro: Some Chinese Characters Not Displaying Properly with Font Fallback

I’m experiencing an issue with font fallback in Unity. Certain Chinese characters are not rendering correctly. When I assign a specific Chinese font directly, the characters display fine. However, when relying on the fallback list, it seems to suddenly stop working. This issue affects proper localization and text rendering in my project.

Steps to produce

  1. Set up a font fallback list including a Simplified Chinese font.
  2. Use a text element with Simplified Chinese characters (e.g., “宝随免激跟踪推改立刻”).
  3. Observe that some characters are missing or not rendering correctly.
  4. Assign the Chinese font directly to the text element and see that it works without issues.
