### Advanced Font Shaping Options
Font shaping is the process which expands font ligatures and applies other
advanced font display features that are encoded in your chosen font, in
order to correctly position and display the appropriate glyphs on your display.
The [HarfBuzz](https://harfbuzz.github.io/) library is used to perform
font shaping.
The `harfbuzz_features` option allows specifying the features to enable when
using harfbuzz for font shaping.
