Looking briefly at the GSUB lookups, I don't see the language-specific lookups I'd expect. In the 1.x font, it looks like we handled this within the 'calt' feature (which is a little odd - I'd have expected it in 'locl' - but perhaps we had a good reason for it at the time, I forget). The good reason is that, at least at the time, MS shaper for Arabic didn't process locl. And it still isn't listed as one of the features supported by their shaper in http://www.microsoft.com/typography/OpenTypeDev/arabic/intro.htm. Anyone know differently? The attached testcase... Thanks. On this subject: I would have expected language-specific forms to work with Graphite rendering since the language table therein appears to work (at least it does with WorldPad -- admittedly using the old Graphite engine): Any suggestions would be welcomed.
