Status: RESOLVED WONTFIX

(Core :: Internationalization, defect)

Description

[Jungshik Shin]

Spin off of bug 162949 and bug 164759
Currently, line-breaking is based on JIS X 4051, but some lang-specific
tailoring may be necessary. The framework is already there
and a draft patch was uploaded  as attachment 96285 [details] [diff] [review]. In addition to that,
the following places have to be modified as outlined in bug 162949 comment #17:

Hey, would it be possible to document the code some in the process?  nsTextFrame
is pretty much unreadable, with very long loops, gotos, and almost no
comments....  Just having an idea of what's going on could be nice...

The bug assignee didn't login in Bugzilla in the last 7 months.
:m_kato, could you have a look please?

We will move line and word breaking algorithm to UAX14/29 rules using ICU4X segmenter. And these don't have lang specific breaking rule without CSS property. So it marks as WONTFIX.
