I consider that a bug. http://docs.racket-lang.org/r5rs-std/r5rs-Z-H-9.html?q=char-numeric%3F#%_idx_490 "The numeric characters are the ten decimal digits." Note that meaning changed in R6RS: "A character is numeric if it has the Unicode “Numeric” property." So the current Racket behaviour matches R6RS. /Jens Axel Tested with: > > ======== > #lang r5rs > > (define (test) > (let again ((i 0)) > (cond ((< i #xD800) > (let ((c (integer->char i))) > (cond ((char-numeric? c) > (display (list i c)) > (newline))) > (again (+ i 1))))))) > ======== -- -- Jens Axel Søgaard _________________________ Racket Developers list: http://lists.racket-lang.org/dev
