About:
libgrapheme is a lightweight, dependency-free C library for UTF-8 and UTF-16 string processing. It provides robust functions for character classification, normalization, and grapheme cluster breaking according to the latest Unicode standards. Designed for simplicity and security, it is ideal for environments where minimal dependencies and correctness are critical.
Key Features:
  • Zero-dependency ANSI C99 library
  • Implements Unicode 15.0 and UAX standards
  • Handles UTF-8 and UTF-16 encoding
  • Provides grapheme boundary, character, and case folding APIs
Use Cases:
  • Building secure string manipulation functions in C applications
  • Implementing Unicode-aware text processing in embedded systems
  • Creating lightweight text editors or terminal tools
Alternatives:
  • libicu – Much larger and more comprehensive, but introduces significant dependencies and complexity.
  • utf8proc – Focuses on normalization and case folding; libgrapheme offers a broader scope of string operations.
