Introduction Using an external pre-processor (built using HarfBuzz) you can achieve affects that are not possible (or, at least, not easy) directly with XeTeX. Here’s a simple example of colouring Arabic vowels – this example is likely to be possible…
Introduction: A very brief post This is an extremely short post to note one way of building the superb HarfBuzz OpenType shaping library as a static library on Windows (i.e., a .lib) – using an elderly version of Visual Studio…
