Questions tagged [harfbuzz]

HarfBuzz is a software development library for shaping of Unicode text (converting Unicode point sequences to glyph indices and positions). The most recent incarnation of HarfBuzz ("New HarfBuzz") targets various font technologies while the first version ("Old HarfBuzz") targeted only OpenType fonts.

It is important to understand that New HarfBuzz, provides only text shaping functionality (converting Unicode point sequences to glyph indices and positions). It does not perform text layout or rendering, so if those functionalities are required, other libraries will have to be used, such as Pango (which incorporates HarfBuzz) for higher-level text layout, and FreeType or Anti-Grain Geometry for text rendering.

The goals for New HarfBuzz, as set by the developers, are for HarfBuzz to be: beautiful, robust, flexible, efficient, portable. Some potential applications that a good-fit for HarfBuzz are: GUI toolkits, web browsers, word processors, designer tools, font design tools, terminal emulators, batch document processors, TeX engines.
