I was looking though Maha Sena's textbook on Tai Tham for Pali, and I noticed that he had a Lao script Pali section that made use of a nukta that seems to me to be indistinguishable from U+0EBA LAO SIGN PALI VIRAMA. Is it therefore in order to use that character for this nukta, just as U+0E3A THAI CHARACTER PHINTHU functions as a nukta?
Now the nukta and the vowels below slightly interact, with the nukta on the left and the vowel below in the right. As U+0EBA has ccc=9 and the Lao vowels below have ccc=118, this seems to be fine. (of course, I may have to wait to find a font that arranges them correctly.) I attach an example of the word "viññūhīti". Richard.
