Hi. The 4.3 version seems interesting with some speed improvements https://github.com/harfbuzz/harfbuzz/releases/tag/4.3.0
May be someone can update HarfBuzz in LibreOffice to the 4.3 version? ps: I would do it myself as Caolan did it in 6ebf46e332facfae5fd6027ec667ccd5993dd493 but I'm not sure if it needs some additional .patch ... Thanks -- Best Regards, Roman Kuznetsov
