Tools for reporting bugs
Harfbuzz hb-view and hb-shape
These are part of the HarfBuzz distribution and can help isolate if an issue is in the app/OS, shaping engine, or font.
hb-view renders the text with the exact font (for example, to see how ligatured characters shape) using your installed version of HarfBuzz.
For example:
hb-view --font-file {path to font} --text-file {path to text file} --output-file '{sample}.png'
hb-shape shows glyph selection and positioning
Fontview
Fontview displays the text.
Fontdiff
Fontdiff displays the text using two versions of the font side by side.
