Question

I have set glyphs to my custom font url but there scenarios which are breaking the font when some character is not found. A character 〜 is not found and then mapbox tries to request from a different range from 0-255 -> some other range but that range does not exist in my font as i only have 0-255 range. How can i add a fallback that either it finds the 〜 and displays or it shows a ? instead of the characters which are not found.

Due to this my map style is breaking.

研究方向: The user requests a fallback for missing glyphs in custom fonts. Investigate glyph loading in Mapbox GL JS, particularly the logic that requests glyph ranges. Look at the source code for font handling (e.g., src/ui/map.js, src/style/style.js) to understand how missing characters are handled. The maintainers need to clarify if a fallback mechanism exists or can be added. Consider adding a configurable fallback font or a placeholder character. Check if similar issues exist or if there is a workaround.
