933631 - Lao support - line break and word boundary detection

Status: RESOLVED DUPLICATE of bug 1719535

(Core :: Layout: Text and Fonts, enhancement)

Description

[robert.rcampbell]

User Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:24.0) Gecko/20100101 Firefox/24.0 (Beta/Release)
Build ID: 20130911155223

Steps to reproduce:

1. Go to laosabbathschool.com
2. Scroll down some.
3. Notice long texts not broken. Double click on line. Lines, not words, selected.


Actual results:

Long texts not broken and words not selected. (Very similar to old Thai issues)

Example:
ພຣະທັມເຮັບເລີຄາດຄະເນລ່ວງໜ້າວ່າຄົນຈະຮູ້ແລະເຂົ້າໃຈເຖິງວຽກງານຂອງປະໂລຫິດໃນສະໄໝຂອງຊົນຊາດອິດສະລາເອນເພື່ອວ່າຜູ້ທີ່ຮັບຈົດໝາຍທີ່ຖືກບັນທຶກໄວ້ໃນພຣະທັມນີ້ຈະສາມາດເຂົ້າໃຈວ່າພຣະເຢຊູຊົງເຮັດສິ່ງໃດສຳລັບພວກເຂົາໃນສະຫວັນ


Expected results:

Words should be detected, and lines broken at the word boundaries. ICU 52.1 can do this now.

A dictionary for this support is at: http://code.google.com/p/lao-dictionary/
The Thai support could be modified to include Lao relatively easily now, via ICU or via the new word-list/dictionary.

Here's a better example: http://laosabbathschool.com/development/ssd/site/blog/zwsp-testing/

If there is anything I can do to help, just let me know. I'm often on mozilla #developers IRC as rcampbelllaos, and would love to help.

This also a problem for Thai.
When would this be fixed?

We've integrated ICU4X segmenter in bug 1719535, which supports word boundaries for Chinese, Japanese, and SE Asian languages (including Lao & Thai).
