Glyph

The Glyph mod changes the font using a Minecraft resource pack.

Glyph automatically generates a resource pack that changes fonts in Minecraft, and when you select your desired font, it automatically modifies default.json. Use the latest version immediately by using the resource pack.

You can import a ttf file.

How to use Glyph mod:

If you have uploaded a ttf font, go to Settings, then Resource Packs,
and apply the glyph_fonts resource pack.

Why use Glyph?

Glyph can use a resource pack to import fonts from older versions into the latest version.
As mentioned earlier, This mod is lightweight because it simply creates a resource pack to add fonts and changes fonts by modifying default.json, so unless there is a mod that overhauls font rendering, the chance of conflicts with other mods is low.
