1024349 - Voiced sound mark of Japanese kana is handled incorrectly with default Japanese font

Status: RESOLVED WONTFIX

(Firefox OS Graveyard :: General, defect)

Attachment: testcase

As discussed in bug 966166 comment 199 and bug 966166 comment 200, the character U+3099 is handled incorrectly. This character will be moved 1em behind the position it should be when combining with Japanese kana.

Jonathan analysed that:
> I believe the problem here occurs because the Japanese font used by default
> on B2G (MotoyaLMaru) doesn't support U+3099, and so this character falls
> back to Droid Sans Fallback; but breaking the font run between the base
> character and the mark results in poor positioning. U+3099 ends up as a
> zero-width glyph, but it's positioned relative to the origin in such a way
> that it overstrikes the *following* base character. :(
