Behdad Esfahbod 9940504e 2018-07-03T14:29:25 [indic] Adjust left-matra repositioning and Halant,ZWJ sequence From the new code (first paragraph is from the OT Devanagari spec.): /* o Reorder matras: * * If a pre-base matra character had been reordered before applying basic * features, the glyph can be moved closer to the main consonant based on * whether half-forms had been formed. Actual position for the matra is * defined as “after last standalone halant glyph, after initial matra * position and before the main consonant”. If ZWJ or ZWNJ follow this * halant, position is moved after it. * * IMPLEMENTATION NOTES: * * It looks like the last sentence is wrong. Testing, with Windows 7 Uniscribe * and Devanagari shows that the behavior is best described as: * * "If ZWJ follows this halant, matra is NOT repositioned after this halant. * If ZWNJ follows this halant, position is moved after it." * * Test case, with Adobe Devanagari or Nirmala UI: * * U+091F,U+094D,U+200C,U+092F,U+093F * (Matra moves to the middle, after ZWNJ.) * * U+091F,U+094D,U+200D,U+092F,U+093F * (Matra does NOT move, stays to the left.) Fixes https://github.com/harfbuzz/harfbuzz/issues/1070 Test case added with Adobe Devanagari.

Behdad Esfahbod e2b87805 2016-12-22T14:40:19 Disable OTL processing for Hebrew if GPOS doesn't have Hebrew subtable New approach to fix this: https://github.com/behdad/harfbuzz/commit/69f9fbc4200442a35484d3c790ae8f4979be5d60 Previous approach was reverted as it was too broad. See context: https://github.com/behdad/harfbuzz/issues/347#issuecomment-267838368 With U+05E9,U+05B8,U+05C1,U+05DC and Arial Unicode, we now (correctly) disable GDEF and GPOS, so we get results very close to Uniscribe, but slightly different since our fallback position logic is not exactly the same: Before: [gid1166=3+991|gid1142=0+737|gid5798=0+1434] After: [gid1166=3+991|gid1142=0@402,-26+0|gid5798=0+1434] Uniscribe: [gid1166=3+991|gid1142=0@348,0+0|gid5798=0+1434]

Behdad Esfahbod fc0daafa 2014-07-23T16:48:51 [indic] Handle old-spec Malayalam reordering with final Halant See comment. Micro-tests added.
Behdad Esfahbod 7cd33f23 2014-07-17T14:22:11 Micro optimization
Behdad Esfahbod e7ce50d9 2014-07-16T12:30:39 [indic] Fix access past end of array
Behdad Esfahbod 7627100f 2014-07-11T14:54:42 Mark unsigned integer literals with the u suffix Simplifies hb_in_range() calls as the type can be inferred. The rest is obsessiveness, I admit.
Behdad Esfahbod 68f72448 2014-06-30T15:46:53 [indic] Remove some more now-unused special-cases
Behdad Esfahbod e79c9489 2014-06-30T15:39:39 [indic] Remove special-casing of U+1CF2,1CF3 These were introduced in a498565cedf0441ae723c5e5969f637d792a15e7, but IndicSyllabicCategory has had the correct value already, so the special code was never needed.
Behdad Esfahbod d743ce78 2014-06-30T15:24:02 [indic-table] Update to Unicode 7.0 data Touch code just enough to preserve previous syllable structure and functionality as closely as possible. Many further cleanups coming later.
Behdad Esfahbod 1d634cbb 2014-06-06T17:55:02 Fix base-position when 'pref' is NOT formed If pre-base reordering Ra is NOT formed (or formed and then broken up), we should consider that Ra as base. This is observable when there's a left matra or dotreph that positions before base. Now, it might be that we shouldn't do this if the Ra happend to form a below form. We can't quite deduce that right now... Micro test added. Also at: https://code.google.com/a/google.com/p/noto-alpha/issues/detail?id=186#c29
Behdad Esfahbod 04dc52fa 2014-06-06T17:28:38 [indic] Recover OT_H undergone ligation and multiplication Sometimes font designers form half/pref/etc consonant forms unconditionally and then undo that conditionally. Try to recover the OT_H classification in those cases. No test number changes expected.
Behdad Esfahbod 39c8201f 2014-06-06T17:19:35 [indic] Improve base re-finding No test numbers change.

Behdad Esfahbod 832a6f99 2014-06-04T16:57:42 [indic] Don't reorder reph/pref if ligature was expanded Normally if you want to, say, conditionally prevent a 'pref', you would use blocking contextual matching. Some designers instead form the 'pref' form, then undo it in context. To detect that we now also remember glyphs that went through MultipleSubst. In the only place that this is used, Uniscribe seems to only care about the "last" transformation between Ligature and Multiple substitions. Ie. if you ligate, expand, and ligate again, it moves the pref, but if you ligate and expand it doesn't. That's why we clear the MULTIPLIED bit when setting LIGATED. Micro-test added. Test: U+0D2F,0D4D,0D30 with font from: [1] https://code.google.com/a/google.com/p/noto-alpha/issues/detail?id=186#c29
Behdad Esfahbod 17c3b809 2014-06-02T15:08:18 [indic] Treat U+A8E0..A8F1 as OT_A instead of OT_VD Apparently they can intermix with other OT_A. Test: U+0915,A8E2,1CD0
Behdad Esfahbod 7977ca17 2014-05-29T15:34:26 [indic] Allow decimal and Brahmi digits as placeholders Tests: U+0967,0951 U+0031,093F
Behdad Esfahbod 52b562a6 2014-05-27T18:18:23 [indic] Clean up a bit No functional change intended.
