how to `read-char` from port using `latin-1` encoding?

[Matthew Butterick]

IIUC when `read-char` reads from a port it assumes the port uses UTF-8 encoding. [1] 

(My Racketuition suggests there might be a parameter called `current-port-encoding` that controls what encoding is applied to the port, but apparently not.)

So instead, one must convert the port explicitly. OK, this seems to work:

(open-input-string (bytes->string/latin-1 (port->bytes port)))

The problem is that I'm reading all the bytes first, which defeats the port-ishness of the operation.

But if I try the promising-sounding `reencode-input-port`:

(reencode-input-port port "latin-1")

This doesn't work, because it relies on `bytes-open-converter`, which apparently doesn't know about `latin-1` encoding (a teeny bit surprising since other racket/base functions deal with this encoding)

Hence the question: is there a smarter way to read characters from a `latin-1` encoded port?

Try "latin1" (no hyphen).

I'm not sure of the standard for these names, but probably Racket's `latin-1` functions are misnamed.

Try using "iso-8859-1" as the name of the encoding, instead of "latin-1." -J

OK thanks. Both "latin1" and "iso-8859-1" do work with `reencode-input-port`.
