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

Thanks Jens Axel. However, the r5rs version appears to be the

Unicode characters, which is what a Racket character represents.
