Hmm, so I played around with this and here's what I think is the

We have some customized break iterator rules in LibreOffice, so we're
using those ones and *not* the built-in icu ones. But we lack a
customized Thai one, so we're using some ultra-generic word breaking
stuff for Thai and not going near the special built-into-icu Thai
iterator :-(

I think this change:
should improve matters a lot. Makes "กุหลาบ" get treated as a single
word in the unit test there now anyway, though the Northern Thai one is
still not considered a single word, that might be due to the oldish icu
we're still using.

After some googling I'm unsure if the "right way to go" to further
improve Thai break iterators is to simply have another go at upgrading
icu to get the latest and greatest there, or for "someone" to have a go
at integrating libthai into LibreOffice and hand off break iteration for
Thai to that. Either way, link above and related unit test give an entry
point to the relevant code.
