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. Richard.
