So why do you need special ASCII functions? That was only suggested in the case that you're going to throw out the Unicode mappings, you at *least* want to keep around ASCII mappings. Scheme will continue to be used in a wide variety of platforms, including embedded systems, so regardless Unicode should be at most optional, not a requirement, just as the full numeric tower is optional. -- Alex
