Ken'ichi, I've finally replaced the Thai word list of unknown origin with a list taken from IBM's ICU4J project which uses the X license. See attached file. In case it is not possible to use this data directly within GNU stuff, I suggest to move the word list into a separate file (together with a license stating that this file is not directly part of Emacs, etc. etc.) which is then read in with thai-update-word-table. Since thai-forward-word is an essential feature for Thai still lacking in Emacs, I ask for inclusion into Emacs right now. Werner
