Summary: [PP] Latin Extended characters rendering problem → [PP][BETA] Latin Extended characters rendering problem
Target Milestone: M16 → M13
Teruko says this is a Beta stopper, so moved from M16 to M13.
Have the fix for Latin Extend A (U+0100-U+017F) except U+012C, U+012D and U+017F
due to the way Apple make their font. The fix use ATSUI in a limited way.
Do not have fix for Latin Extended B or IPA range. But it should be treat as
lower priority...
Whiteboard: fix for some chars in local tree.
Target Milestone: M13 → M20
I check in the fix for the Latin Extend A part. (as the limitation stated
above). Since the remaining part is low priority, move it to M20.
Keywords: pp
Due to Beta indication in Summary, putting beta1 into keyword field.
Keywords: beta1
Put on PDT- per ftang comments.
Whiteboard: fix for some chars in local tree. → [PDT-]fix for some chars in local tree.
Summary: [PP][BETA] Latin Extended characters rendering problem → Latin Extended characters rendering problem
FYI, these are the descriptive names for the Latin Extend A characters
mentioned earlier:
  U+012C: LATIN CAPITAL LETTER I WITH BREVE
  U+012D: LATIN SMALL LETTER I WITH BREVE
  U+017F: LATIN SMALL LETTER LONG S

We could choose to tranliterate these to a similar ASCII glyph.

gary no longer work for us. reassing to ftang
Assignee: garywade → ftang
Status: ASSIGNED → NEW
We already did some transliteration now. Most of the Latin characters in this
range which could easily find a ASCII as base character are transliterate. I
don't think the rest of the characters are worth for us to fix for nsbeta1. Keep
this as Futre. Mark it P5. nsbeta1- for this bug.
