> I cannot find isWordTextBreak anywhere in the WebKit source code. Is this something you're working on now? For the record GTK+ uses ICU by default, so there shouldn't be much in the way of implementation.

It is added in r110965
under Source/WebCore/platform/text/TextBreakIterator.h.

If you look at its implementation under TextBreakIteratorICU.cpp,
basically, it is checking the current word break iterator just pass over a word.
For example, "abc def", both positions "abc| |def" are word break positions,
but isWordTextBreak returns true for "abc| def" since the break iterator just pass over "abc". And it returns false for "abc |def" since the break iterator just pass over a space.

If GTK+ uses ICU, that should be easy to implemented.
