The non-cooperation between char-numeric? and string->number is very annoying.
I had to resort to: (define (my-char-numeric? c) (char<=? #\0 c #\9)) Maybe I am missing a function similar to my-char-numeric? somewhere in the Racket docs? FWIW, my humble opinion is that char-numeric? should be defined as the my- version above. The Unicode category, if that's what one wants, can be accessed with char-general-category.
