A while ago I blogged about the ongoing work to add support for complex text shaping to the Harfbuzz library. After we have ported Qt’s text shapers down to the Harfbuzz library level we worked on making Qt use them through the new interface. Now we have finally completed the porting for all supported platforms […]
