HarfBuzz

HarfBuzz is an OpenType text shaping engine. Using the HarfBuzz library allows programs to convert a sequence of Unicode input into properly formatted and positioned glyph output—for any writing system and language.

The canonical source-code tree is available at github.com/harfbuzz/harfbuzz and is also available at cgit.freedesktop.org/harfbuzz. See Downloading HarfBuzz for release tarballs.
