Author	SHA1	Message	Date
Garret Rieger	2bdd903c69	[subset] limit the max codepoint value to the unicode limit. ... When collecting all codepoints in the cmap avoid using large amount of memory for fonts that declare coverage over all 32 bit integers.	6 years ago
Garret Rieger	7278d9df30	[subset] Add hb_ot_layout_collect_features to harfbuzz-sections.txt. ... Add the fuzzer test case for feature collection timeout.	6 years ago

Behdad Esfahbod	fe099a844b	[test] Add Khmer tests, with NotoSansKhmer-Regular.ttf ... Note that there's minor positioning differences, and ONE reordering difference between what we get for these and what Uniscribe gets. Probably same as what's described in commit message for 1a96cc825d	6 years ago

Behdad Esfahbod	9940504e93	[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.	6 years ago

Behdad Esfahbod	44b6c77c64	Try fixing linking again ... Before 1.7.5, we were setting -fno-exceptions etc on CXXFLAGS. In 1.7.6 we set it as CPPFLAGS. Try fixing.
