The key word here is 'preferred'. Your reply, while not completely
clear, confirms my view that Unicode does not *specify* an overall
character ordering for Khmer, despite the section's having a BNF regexp
for Khmer syllables - B{R|C}{S{R}}*{{Z}V}{O}{S}.

But as you acknowledge, the specification only covers a strict subset of
legitimate Khmer script text, even of text composed of encoded Khmer
characters. It excludes some text given in TUS Section 16.4. Indeed,
Section 7.4 of the proposal to ICANN even excludes the new spelling of
the word ឱ្យ (ooy, give) - <U+17B1 KHMER INDEPENDENT VOWEL QOO TYPE ONE,
U+17D2 KHMER SIGN COENG, U+1799 KHMER LETTER YO>, for U+17B1 is not a
consonant!
I have ignored the logical gaps in your reply; nothing in the *Unicode*
standard prohibits or deprecates the sequence <U+1781, U+17C6, U+17D2,
U+1789, U+17BB>, even though it does not satisfy the regexp I quoted
above.

I do not support the heresy that COENG may only occur between
consonants.
I do wonder if the Khmer Generation Panel opened their Pali grammars.
How would they propose to write the accusative singular of nouns in
-i? The accusative singular of non-neuter nouns ends in -iṁ, which I
would expect to be written <U+17B7 KHMER VOWEL SIGN I, U+17C6 KHMER SIGN
NIKAHIT>, which is what I perceive at the end of a line in the middle
of the second left-hand page at
http://watkhemararatanaram.org/tipitaka/viney_beidok_05b.php . Do they
expect one to use U+17B9 KHMER VOWEL SIGN Y? (Thai scholars once had
to resort to such an expedient.)
Richard.
