Why forbid it?  Some programs deal exclusively with binary input.

It is not necessarily an error to invoke read-u8 on a textual port, if it is
also a binary port.  We expect both to often be the case.

Most people are much more ignorant about language than they are about
[other subjects], but they reckon that because they can talk and read and
write, their opinions about talking and reading and writing are as well
informed as anybody's.  And since I have DNA, I'm entitled to carry on at
length about genetics without bothering to learn anything about it.  Not.
