There are, of course, claims that these should be letters, especially jña
with its rather odd pronunciations. For ks.a I'd put the break at the upper
point where the curve crosses itself. For jña I'd say the final downward
stroke was the ña part.

No-one was suggesting this. OpenType layout controls may provide crude
positioning information for cursor placement within a ligature, but 2-D
placement is really needed, as for example in the Word equation editor.
While ks.a shows the normal top-to-bottom ordering, this jña is almost
right-to-left! The point is that the computer has to be told the analysis
of the ligature.
