It's possible to use it for the bulk of case folding, especially if the
program only supports a specific repertoire.

For specialist tasks, exploiting arithmetic relationships make sense.
I would expect that most ASCII clones are handled that way. The
problem is that manually constructed lookup tables are prone to human
