To build paths for a convention other than the current machine's convention, you have to work in bytes instead of strings.
(define (bs->p bs) (bytes->path bs 'unix)) (build-path/convention-type 'unix (bs->p #"/") (bs->p #"foo") (bs->p #"bar")) Roughly, strings don't work, because they have to be converted to bytes using the locale's default encoding. Although strings are allowed for the current platform's convention on the assumption that the current locale's encoding is the right one, we've avoided building in any assumption about the encoding for the other convention.
