Non-Latinness! The same applies mutatis mutandis to Hebrew geresh
and Devanagari nukta.

To me it is very striking that the choice of consonants for the
application of Devanagari nukta and the creation of new consonants
in Thai coincide. Copying? The most striking parallels are the
creation of <z> (so so in Thai) from <j> (cho chang in Thai) rather
than <d> (tho tahan in Thai), and the creation of consonants for
voiced fricatives from voiced stops rather than voiced aspirate
stops. (The consonants for voiceless fricatives have been created
from the consonants for voiceless aspirates.)

English <wh> is a bit of a problem, as <w> isn't Latin, but then
it's also curious in that it is, at least in places, [hw]. I think
<wh> is best regarded as a degeneration of <hw>, attracted by the
other digraphs with <h>.

As to English <sh> and <th>, I could pedanticaly suggest that 'h' in
<sh> and <th> represents half-way Irish-style lenition for 'sh'
and 'th' - there are lenition sequences [s] > [S] > [h] and [t] >
