Korean Font Rendering Issue After Session Time - TextMeshPro

[yunhee]

Hello [Developer/Support Team],

I would like to report a recurring issue with Korean font rendering in the game, which appears to be related to TextMeshPro.

Issue Description:
- Korean characters display correctly for a certain period after launching the game.
- However, after some time has passed, characters begin to break or disappear, as shown in the attached screenshot.
- The issue manifests as missing glyphs, replaced by empty squares or boxes.
 

Steps I Have Taken:
1. Imported and applied NotoSansKr font.
2. Imported and applied Gothic font.
3. Changed system locale and language settings to Korean.
4. Switched Korean input methods (IME).
 

Results:
- Despite these changes, the issue persists.
- The problem does not occur immediately, but only after a certain duration or scene transitions.
- This suggests that the font asset or glyph cache may be unloaded from memory over time.
 

Impact:
- Korean text becomes unreadable, severely affecting communication and usability for Korean-speaking users.
- This is especially problematic in chat interfaces and UI elements.

Request:
- Please investigate whether TextMeshPro font assets are being prematurely unloaded or mismanaged.
- A patch or configuration option to keep specific fonts cached would be greatly appreciated.
- If there is a recommended workaround or fix, I would be happy to apply it.

Thank you for your attention to this issue.

Best regards,
