Behdad Esfahbod 35d410f2 2018-10-29T14:45:44 Remove ASSERT_POD Newer compilers / language allows structs with constructor in union. So, this was not actually testing anything. Indeed, the recent change in DISALLOW_COPY *is* making some of our types non-POD. That broke some bots. Just remove this since it wasn't doing much, and I'd rather have DISALLOW_COPY.

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.
