A small C library for rendering Unicode text in OpenGL using a single texture atlas and a single vertex buffer, built on top of FreeType. It provides glyph packing, font caching, markup-based text properties, and optional distance-field text rendering.

Use cases

• render text in an OpenGL application
• draw Unicode strings with a single texture and vertex buffer
• pack font glyphs into a texture atlas
• render fonts without FreeType at runtime using pregenerated headers
• display styled text with colors and underline in OpenGL
• add font rendering to a game engine in C

When to choose

• you need lightweight, low-level text rendering in OpenGL from C or C++
• you want a single texture atlas and vertex buffer for efficient glyph drawing
• you need Unicode support with markup-style text properties
• you want to bake fonts into headers to avoid a FreeType runtime dependency

When to avoid

• you need a full GUI text layout engine with complex shaping (use HarfBuzz-based stacks)
• you are not working with OpenGL directly
• you need DirectWrite/CoreText/Direct2D native platform text rendering
• you want a high-level UI framework rather than a rendering primitive
