Sorry the last patch has a minor problem - it treats the whole of 0x0EXX as
Thai (0x0E80-0x0EFF is Laos). while it is unlikely(?) somebody might want to do
both - is there a LaTeX package for Laos? - we better do it correctly.
BTW, your TUGboat article 11 years ago says the word-breaking algorithm might
be in the next version of emacs... That hadn't happened yet? :-).

Subject: [PATCH] [cjk-enc.el] Correct minor issue with last commit.
Thai is 0x0E00-0x0E7F only. The previous commit mistakenly
treats all of 0x0EXX (the upper range being Laos) as Thai.
