;; Printable string (no special characters)
((and (string? x)
(eq? (string-length (string-delete x char-set:printing)) 0))
x)
It's trying to determine if the string contains any non-printable chars.
How can I write this [...]
Use ‘and-map’ with a predicate wrapped around ‘char-set:printing’ directly.
