Ticket 176: Are string ports exclusively character ports?

From scheme-reports discussion list, by John Cowan:

Jeronimo Pellegrini scripsit: > According to Section 6.7.1, "Conversely, not all character ports are > binary ports -- for example, the /string ports/ discussed below". It > is not really clear to wether the document *requires* string ports not > to be binary or if it was just an example of a port that *could* be > character but not binary.

I haven't thought about it, but I guess it *could* be the latter, if the environment provides a default encoding for string ports.
