## What it is
A collection of single-header, permissively-licensed C/C++ libraries in the stb style. Its main library, kb_text_shape.h, provides Unicode text segmentation (line, word, grapheme, script, direction breaking) and HarfBuzz-like OpenType text shaping for complex scripts and ligatures.

## Use cases
- shape Arabic or Hindi text in a custom renderer
- break Unicode text into graphemes and words in C
- implement complex script layout without HarfBuzz
- check whether a font covers a given string
- render bidirectional text in a game or GUI
- add ligature and OpenType feature support to a text editor

## When to choose
- you need text shaping or Unicode segmentation in C/C++ with a small, embeddable single-header dependency
- you already handle rasterization and font loading and only need glyph placement
- you want a permissive Zlib license for commercial or embedded use

## When to avoid
- you need full paragraph layout, line wrapping, or font selection from the system
- you need glyph rasterization included
- you work outside C/C++

## Facets
- artifact type: library
- maturity: active
- function: nlp, internationalization, parser
- domain: text-editors, developer-tools
- platform: c, cpp, cross-platform
- tags: single-header, text-shaping, unicode, opentype, harfbuzz-alternative, stb-style, font-rendering, internationalization
