Behdad Esfahbod bed201d2b8 Update for latest Unicode 9 data files 2016-06-06 14:14:24 -07:00
Behdad Esfahbod 30e6e29f0f [indic/use] Move Javanese from Indic shaper to USE 
Fixes https://github.com/behdad/harfbuzz/issues/243

With javatext.ttf, the reodering medial Ra gets its advance width
zero'ed in Uniscribe implementation, and the font adds the advance
back.  Our Indic shaper does not do that, but USE does.  So, route
Javanese through USE.  That's what Microsoft does anyway.  Test:

  U+A9A5,U+A9BA

This also seems to fix the following sequence, and variations thereof:

  U+A99F,U+A9C0,U+A9A2,U+A9BF

Behdad Esfahbod c09a607a84 Use hb_in_range() for arabic and indic tables 
Though, looks like gcc was smart enough to produce the same code
before...
