Maybe this is a bit related to Khaled’s question earlier about control characters inside ligatures, but I wanted to start a new thread.
When I shape text with Noto Nastaliq, I notice a bunch of zero-width glyphs generated $> hb-unicode-encode U+06CC,U+06C1 | hb-shape notonastaliq.ttf [HehFin=1+472|TwoDotsBelowNS=0@310,-383+0|sp2=0+0|BehxIni.outS1=0@0,-68+731] 1. What is the purpose of these zero-width glyphs? 2. If I am rendering the shaped output to a PDF file (for e.g. when using Harfbuzz with LuaTeX), do I need to care about these zero-width glyphs at all? How will they affect rendering _______________________________________________ HarfBuzz mailing list [email protected] http://lists.freedesktop.org/mailman/listinfo/harfbuzz
