I will check.

Did XeTeX accidentally become more "clever" about normalisation rules
during the last year? Or maybe it started doing automatic word
splitting and now automatically inserts spaces in the middle of
hyphenation patterns as well? It could also be related to changes in
ICU. It's weird because I don't see the pattern "ก4ข" appear anywhere.
There are these patterns:
35 ก4ขค
37 ก4ขช
39 ก4ขณ
42 ก4ขบ
44 ก4ขภ
46 ก4ขม
52 ก4ขเ
55 ก4ข์
but nowhere I see the isolated string reported as duplicate.

In case anything of the above is true, we have a problem that we need
to address before TL 2015 comes out.
