A lightweight, dependency-free TrueType font rendering library written in C99.
libschrift is a lightweight TrueType font rendering library written in C99. It provides a simple API for rendering Unicode text with TrueType and OpenType fonts while prioritizing correctness and security. The library is designed to be artifact-free and robust against malformed input.
C developers working on embedded systems, terminal applications, or lightweight graphical interfaces who need reliable font rendering without heavy dependencies like FreeType.
Developers choose libschrift for its minimal codebase, lack of external dependencies, and focus on security and correctness. It's ideal for projects where simplicity, portability, and reliability are more important than advanced typographic features.

At approximately 1,500 lines of code, libschrift is easy to audit and integrate, reducing binary size and complexity for embedded or lightweight projects.
Only requires the C standard library, with optional POSIX/WINAPI for memory mapping, ensuring high portability and avoiding dependency management headaches.
Tested on Linux, BSD, Windows, iOS, and macOS with C99 compilers, making it a reliable choice for cross-platform C applications.
Designed to not crash, leak memory, or expose vulnerabilities on malformed input, addressing common security issues in font rendering libraries.
Exclusively supports Unicode for consistent and artifact-free international text rendering, simplifying encoding handling.
Lacks hinting, which can result in blurry or misaligned text at small sizes compared to libraries like FreeType2, impacting visual quality in dense interfaces.
Admitted in the README as a missing feature, libschrift does not handle right-to-left languages, limiting its use for global applications.
Only supports TrueType and some OpenType fonts, excluding bitmap, PostScript, and color fonts, which restricts font choice in diverse projects.
Relies on a man page and source code examples for documentation, which may be insufficient for developers new to font rendering without more detailed guides.
