If you are asking whether the "word separator character" I mentioned should be U+00A0, I don't think that would be a good idea for Thai since U+00A0 is supposed to be rendered as a visible space (like U+0020) but without breaking lines between the surrounding words. My understanding is that visible spaces are not used in Thai. So U+00A0 would do exactly the wrong thing for Thai, whereas U+200B would do the right thing (indicating a word boundary without displaying a space). This is also officially recommended by the Unicode Standard. -Doug Ewell Fullerton, California
