Asho Chin needs #8

Closed mhosken closed 5 years ago

mhosken commented 7 years ago

Asho Chin: csh

sequences to support: U+103E U+1060, U+103D U+1060 probably needing their own ligatures.
The preferred form of U+103E is slanted with a 90 degree foot.
Also they like U+106D to be closed at the top.
They also have tone marks after U+1038. Particularly U+1069, U+106A, U+106C. These currently fall foul of the sequence checker. Apparently this is a bug in UTN#11, and the tone marks should occur after U+1038 in all cases and not before.
U+1061 U+103D should render correctly but doesn't.

See enclosed PDF Asho_Unicode_codes_and_combinations.pdf

Just to clarify; the preferred form of U+ 103E is vertical when alone; when combined with other descenders, I'm seeing some vertical, some slanted with 90 degree foot, some slanted with flat foot - I'm not sure if there is consensus on a preferred form. consonant combinations

Need a clear spec - a list of all the new glyphs that are needed, as in:

glyphname - encoding - description uni106d.csh - (none) - as uni106d but closed at top

mhosken commented 6 years ago

New glyphs of which none are encoded:

u106D.csh - as u106D but closed at top as per column 3 in Lesson 1 in picture above u103E_u106D.csh - ligature diacritic with APs as per u103E and design as per chart above (bottom row first cell). Note u103E.slanth u103D_u106D.csh - ligature diacritic with APs as per u103D and design as per chart above (6th row first cell)

Design shape questions. Which of these do you prefer and why and how would you modify it to make it even better? 106D.csh feedback.pdf

mhosken commented 5 years ago

Problem is that the shaper is inserting a dotted circle between 103E and 1060. Also need to allows tone marks after 1038. Need to follow up with harfbuzz.

On U+1061 move attachment point BS left so U+103D positions in the proper location. Check positioning of other marks that have BS.

mhosken commented 5 years ago

The shaping for all this works in Graphite, but not in OT mym2 due to a bug in mym2.
