> Xiaomei commented to me in person that one of the ways that FF gets to their superior behavior is by "cheating" and defining word boundaries as spaces.  Which is not true for languages like Japanese (which don't have spaces) and thus require use of a heuristic (like the one provided by ICU).

Firefox implements control-arrow moves caret by word visually.
It treats space as word breaker, which is not completely right for CJK languages, and it simplifies the process a bit. But simply using space as word boundary is not the reason that they achieve the superior behavior. They did a good job, I have to say. 

We use word breaker which break words logically, which made it a bit complicated than what Firefox does, but I do not think we should move backward.
