109-A38 Asmus Freytag Use the information in L2/06-371 to propose linebreak property updates. L2/06-371 In progress

In response to the action item above, I submit this document for discussion at the upcoming  UTC meeting #110.

After analyzing the review document L2/06-371, I propose the following updates:


 
1A1E       BUGINESE PALLAWA

Change from BA -> AL

The review states that no break occurs after this character - unfortunately
the reviewer did not give this character more than a short mention.

 
1802                 MONGOLIAN COMMA
1803 MONGOLIAN FULL STOP
1808            MONGOLIAN MANCHU COMMA
1809            MONGOLIAN MANCHU FULL STOP

Change from BA -> EX

Since Mongolian is likely to occur in mixed text with Chinese ideographs, it is
important to make sure that these characters do not appear at the beginning
of a line, even after a space. (That is the main difference between EX and BA).


 
2CF9              COPTIC OLD NUBIAN FULL STOP
2CFE           COPTIC FULL STOP

Change from BA -> EX

The assertion from the Coptic experts is that spaces before such punctuation
should not allow a break.

Ethiopic line break

Ethiopic line break seems to have some peculiarities all of its own. In fact the
reviewer makes the case that Ethiopic essentially works like ideographs,
i.e. allowing line breaks after every syllable, without indication of hyphenation.
This requires further follow up.
