Behdad Esfahbod deeb540a74 [test] Ignore tests with DOTTED CIRCLE in the output 2012-07-19 11:30:48 -04:00
Behdad Esfahbod 422ecd2d3c [Indic] Accept a forced Rakar sequence at the end of syllable
In Sinhala, Rakar is formed by Al-Lakuna,ZWJ,Ra.  If you put that at the
end of a Consonant,Matra syllable, you get a dotted-circle from
Uniscribe.  Apparently adding a ZWJ before the Al-Lakuna "fixes" that.
And people have been encoding that sequence...  So, allow a forced
"ZWJ,Virama,ZWJ,Ra" sequence at the of syllables.

Fixes some 100 or more of Sinhala failures.  Now at 622 only (0.23%).

Behdad Esfahbod 10cdc94eee [Indic] In final reordering, find base, even if it disappeared
POS_BASE can disappear if base ligated backward.  Define base as last
with position not after base.

Fixes a few hundred of Sinhala failures with Iskoola Pota.

Behdad Esfahbod 3285e107c9 [Indic] Implement Sinhala "Al Lakuna" Reph behavior

Behdad Esfahbod 0201e0a464 [Indic] Apply 'cfar' for Khmer
Mark stuff after a pre-base reordering Ro 'cfar'.  Used in Khmer.
This allows distinguishing the following cases with MS Khmer fonts:

  U+1784,U+17D2,U+179A,U+17D2,U+1782
  U+1784,U+17D2,U+1782,U+17D2,U+179A

Behdad Esfahbod 55f70ebfb9 [Indic] Position final subjoined consonants (and vowels) after matras
In Khmer, a final subjoined consonant or independent vowel can occur
after matras.  This final subjoined thing should NOT be reordered to
before the matra even though it's subjoined.

Fixes another 1k of the Khmer failures.  Not much left really.

Behdad Esfahbod c50ed71e9a [Indic] Recategorize Khmer coeng sign as a separate category OT_Coeng
Amend the syllable structure to allow a final subscripted consonant
(Coeng+C) and a final subscripted independent vowel (Coeng+V).
Fixes another 2k of Khmer failures.

Behdad Esfahbod 74ccc6a132 [Indic] Move Halant with after-base consonants
Normally, we attach the Halant to the previous character and move it
with it.  For after-base consonants however, the Halant "belongs" to the
consonant after, so attach it so.

This fixes Bengali sequences involving post-base consonant Ya, which
should ligate with the Halant to form Ya Phala, but previously a
reordered matras was blocking the ligation.

Behdad Esfahbod d5c4edcdd6 [Indic] Apply presentation-forms features all at once
Seems like this is what Uniscribe is doing, and does not break any fonts
we tested (with Devanagari, Malayalam, Khmer, and Bengali), while fixing
some Ra Phala sequences for Bengali with Vrinda.  Fixes another 2% of
Bengali failures (a couple more to go).

Behdad Esfahbod c071b99f15 [Indic] Add test for Left Matra with Halant
Uniscribe doesn't move the Halant, we do.  And do a broken job of it now.

Behdad Esfahbod b20c9ebaf5 [Indic] Add test for matra group
The spec says: "[{M}+[N]+[H]]", and that's what Uniscribe implements.
We instead do: "{M+[N]+[H]}", which means we allow Nukta and Halant
after all Matras, not just the last one.  It makes more sense.

Behdad Esfahbod 61a58e26a5 [Indic] Add tricky reordering test cases
In the case of Consonant,LeftMatra,Halant, Uniscribe leaves the Halant
where it is, but we want to move it with the Matra as that makes more
logical sense.

Behdad Esfahbod 585b107cde Add test caes for a minority language using Bengali
U+0985 BENGALI LETTER A followed by U+09D7 BENGALI AU LENGTH MARK.
According to Bobby de Vos on the mailing list, this results in a dotted
circle with most shaping engines, but is a legitimate sequence in this
minority language.

We reached the consensus on the list to NOT implement dotted-circle
in HarfBuzz.
