Thank you to every one who's offered me advice.

Ah well, I'll just have to try to get Thai spell-checking working for
myself and then worry about sharing my changes - assuming I succeed.

It's definitely going through a Siamese-specific word-breaker for
line-breaking.  For example the two-syllable Thai word กุหลาบ
'rose' moves to the next line, but when I convert it to the Northern
Thai form กุ๊หลาบ (not the spelling I'd favour) by adding a
(non-spacing) tone mark, it's promptly broken between lines along the
syllable boundary, although the first syllable does not constitute a
word, at least not one recorded in the Royal Institute Dictionary. I'm
glad to find that inserting U+2060 WJ prevents that break. The
spell-checker seems to break up a phrase consisting of just กุหลาบ into 3 or 4 words.

Richard.
