The complexity is comparable. The complexity in Indian languages is that
the glyph is not complete, until you've typed 2-3 more key strokes,
which result in the generation of 2-3 unicode characters. But juxtaposing
the glyphs corresponding to those characters doesn't result in a readable
"Indian character".
In CJK too, you need to wait until 2-3 key strokes are entered, before
mapping that sequence to one of a thousand symbols using a dictionary
lookup.
For Indian languages, the problem is not that of having insufficient
allocation of the unicode space. We have enough room to implement
string manipulation libraries for example. The problem is that we
can't just blindly index the encoding into the font file to get a glyph.
One might need to index a group of 2-3 encodings into the font file to
get a drawable glyph. X seems to allow this:
man XContextDependentDrawing
