John. I appreciate your detailed answers but wish to delve deeper if
I may. Tamil also has an array, a matrix of syllables, a syllabary,
so they call it. Tamil also has fewer phonemes than other Indic
languages, both Indic and Dravidian. It has fewer syllables than
Korean. I realize that the large number of Indic scripts is
probably the biggest argument against precomposed units.

The old typewriter input method, which we also used, had visual
sequence input and while useless on the internet and no good for
ligatures, shaping and rendering has a certain logic to it - it
imitated handwriting.
