There is a font rendering issue with player nicknames containing CJK/Asian characters (hieroglyphs). The game client lacks proper fallback font support for these Unicode character ranges, causing two distinct issues:

1. System chat notifications (e.g., player joined/left messages) become visually broken or misformatted when displaying these names.

2. The 3D nametag/marker above the player in the game world displays a blank white diamond symbol instead of rendering the name or a clean fallback string.

Steps to Reproduce:

1. Join a multiplayer server with a user profile containing CJK characters/hieroglyphs in their nickname (or have a player with such a name join).

2. Observe system notifications in the chat box regarding that player joining/leaving.

3. Look directly at the player in the 3D world to inspect their overhead nametag/marker.

Expected Result: Player nicknames should either correctly render CJK characters using an appropriate fallback font, or safely sanitize/strip unsupported characters to prevent UI breaks and missing glyph symbols (``).

Actual Result: Chat formatting breaks on system messages containing these characters, and overhead 3D nametags render only a white replacement diamond.
