Ah. Missing entries in unicode-letters.def/tex could easily explain
the behaviour we are seeing. It could be that the character
immediately following "ก4ข" is not/no longer defined to be a letter
(it might indeed be an accent or so).

The changes between unicode-letters.tex and unicode-letters.def are
too big to be able to diagnose anything quickly.
