Well!!! here is my comment.
As Thai person speaking about arabic language, arabic vowels (fatha, damma,
kasra, fathatan, dammatan, kasratan) will be displayed on top of consonant
like Cons + vowel.

Also, they can have cons + shadda + vowel but I don't think the sequence,
cons + vowel + shadda is the right sequence. So, the same issue which is
existed in arabic script.

How about Davanagari ?

It has the sequence, cons + vowel + candra. I don't think it's the
right sequence of cons + candra + vowel. Shouldn't they be displayed the same ?

That's correct but the application needs to be reminded that everytime to
display line, it needs to pass the whole logical text stream to wcswidth()
and wcwidth() alone shouldn't be enough right ?

Not quite sure if I understand this question.
