Actually, 1×n is all that is required, as long as the mappings are
bijectional, but this requires two passes. Firstly to convert to ITRANS,
then secondly to the desired script. I can identify one instance where the
mapping is not bijectional, as ব in Bengali stands for both ब and व in
Devanagari, and this has already been mentioned here, I believe, but even
so, a set of n×n mappings doesn't help this situation.
