[racket-users] custom byte encoders?

[je...@lisp.sh]

Is it possible to make your own byte encoder? Section 4.5.4 of the 
reference talks about them and describes the handful of built-in ones. I 
don't see a way of making my own byte encoders, though. I'd like to have my 
own way of validating bytes and performing replacements, similar to what is 
done with the "UTF-8-permissive" encoder (for example, certain junk 
characters get replaced by #\uFFFD), but I'd like to do a bit more than 
that. For example, I'd like replace some exotic but otherwise valid UTF-8 
characters with #\uFFFD. It seems that the only way to do that is to write 
my own custom input (or output) port, with the validation/replacement logic 
contained within the custom port's peek/read-bytes/write-bytes procedures. 
Or perhaps I overlooking something?

This is the second time I’ve heard of matrix.org this week. Time to check it 
out.

 The racket discord is managed quite well, I think it should be added to
 the racket website so that newcomers can find it easier, just a thought.
 
 Maybe below the link to slack?
