This means that QF should support more exotic fonts without any issue (once the rest of the text handling system is up to snuff) as HarfBuzz does all the hard work of handling OpenType, Graphite, etc text shaping, including kerning (when enabled). Also, font loading now loads all the glyphs into the atlas (preload is gone).
