Hmm.. a year ago Martin Hosken introduced char.txt and commented out the
use of SpacingMark and Prepend according to UAX #29 updates, along with
changes in breakiterator script identification. So we already have the
changed behavior since then. It seems that so far no Thai user
complained, so maybe this is indeed desired. Or never was used with the
internal ICU, i.e. on Windows.

Great, thanks. Though not exactly needed because of the above I changed
things to follow the same pattern, which allows to easily reintroduce
the Prepend set if needed.
