I agree with this view.
The only gap that I can "point" to is the fact that there is no
_comprehensive_ *documentation* of the "A+B+C+ ..x" model and their basis.
We attempted this in 2001 and portions are available in the TDIL magazines
for 2002 (see Mahesh's link) . The Late Dr. Joshi was an expert on these
aspects of Indic orthography. We continue to act on his goals.
I also want to re-iterate that "glyph-formation" is connected with the
Input Method. The Sinhala approach of forming their characters - while
almost identical to those of Indian scripts - and subject to the same
principles - is determined by slight changes in their keyboard design. (
e.g. the "Kombuva" range of "Two-part or Split matras" which are similar to
those in Tamil and Bengali are generated in visual sequence and not
linguistic sequence. )
So, while the basis for character-generation would be the same in Sinhala.
Its handling by the Layout Engine would be different.
Regards,
Abhijit Dutta
