Open the attached test case.

The word segmentation for most ports does not work for CJK languages. 
The correct segmentation when cursor is at every character boundary is the one in "title" attribute.
But the word segmentation result for most ports is single character each word.

For those ports that use ICU,
ICU bug to upstream Chrome's CJK segmentation patch is http://bugs.icu-project.org/trac/ticket/2229
After upstream and Apple picks it up in next version of Mac OS X, Mac and Win port will work correctly.

But there are webkit ports that do not use ICU (e.g. Qt, GTK), in which the port itself should take care of the word segmentation.
