You can't even case Latin that way. Unless maybe you only care about English.

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 error.
