Jonathan Kew 391934db0a [unicode] Exclude the Jamo Filler characters from Default_Ignorable, as some fonts want these to be visible/spacing glyphs. 2014-01-20 10:37:32 +00:00

Jonathan Kew 103436838d [hangul] Apply the appropriate *jmo features to decomposed syllables, including Old Hangul sequences that don't have Unicode compositions. Merge clusters in decomposed syllables. 2014-01-20 10:35:07 +00:00

Behdad Esfahbod 32478656ce [hangul] Tighten up character categories 
I had tried to expand to fill the blocks, but that sounds wrong in
retrospect.

Behdad Esfahbod 3d6ca0d32e [ot] Simplify normalization_preference again 
No shaper has more than one behavior re this, so no need for a callback.

Behdad Esfahbod c98b7183f7 [ot] Add Hangul shaper 
Not exhaustively tested, but I think I got the intended logic
right.

The logic can perhaps be simplified.  Maybe we should disabled
normalization with this shaper.  Then again, for now focusing on
correctness.

Behdad Esfahbod 76fff252a9 Don't form fractions if only one of numr/dnom exist 2013-12-22 17:55:59 -05:00
Behdad Esfahbod 3aeee519f0 Bug 72698 - Automatically support frac / numr / dnom 
When seeing U+2044 FRACTION SLASH in the text, find decimal
digits (Unicode General Category Decimal_Number) around it,
and mark the pre-slash digits with 'numr' feature, the post-slash
digits with 'dnom' feature, and the whole sequence with 'frac'
feature.

This beautifully renders fractions with major Windows fonts,
and any other font that implements those features (numr/dnom is
enough for most fonts.)

Not the fastest way to do this, but good enough for a start.

Khaled Hosny c8213c6198 [coretext] Avoid font fallback with CoreText shaper 
CoreText does automatic font fallback (AKA "cascading") for  characters
not supported by the requested font, and provides no way to turn it off,
so detect if the returned run uses a font other than the requested one
and fill in the buffer with .notdef glyphs instead of random indices
glyph from a different font.

Behdad Esfahbod 9174a9db5c [myanmar] Allow punctuation clusters 
The spec and Uniscribe don't allow these, but UTN#11
specifically says the sequence U+104B,U+1038 is valid.
As such, allow all "P V" sequences.  There's about
eight sequences that match that structure, but Roozbeh
thinks it's fine to allow all of them.

Test case: U+104B, U+1038

Behdad Esfahbod 096b71e8ef [myanmar] Mark U+104E MYANMAR SYMBOL AFOREMENTIONED as Consonant 
The spec and Uniscribe treat it as consonant in the grammar, but
it's not in IndicSyllableCategory.txt, so fix up.

Test sequence: U+1004,U+103A,U+1039,U+104E

Behdad Esfahbod d2da5e0b4b [myanmar] Relax pwo-tone group a bit 
This is broken sequence according to OpenType spec, Uniscribe,
and current HarfBuzz implementation.  But Roozbeh says this
is a valid sequence, so allow it.  There are multiple
"(DB As?)?" constructs in the grammar, but Roozbeh thinks only
this one needs changing.

Test case: 1014,1063,103A
