This is very similar to bug 24342, but happens for different characters. Moving insertion point left or right shouldn't jump over several glyphs, even if those form an extended grapheme cluster. ICU has a special case for those Thai characters now, see <http://source.icu-project.org/repos/icu/icu/trunk/source/data/brkitr/char_th.txt>. We should do the same. Patch with a test forthcoming.
