byte-to-string

byte-to-string

[Chong Yidong]

What's the purpose of the new byte-to-string function?  I'm trying to
document it, but the docstring is uninformative about what it can be
used for.

Also, if the integer argument is supposed to be a byte, shouldn't it be
error to give it something larger than 255?  Instead the function
returns something, but I have no idea what that string represents.

A bit of experimentation reveals that (byte-to-string n) returns the
same as (byte-to-string (mod n 256)). Maybe that is useful, I don't
know.

IIUC it's the equivalent of unibyte-string (i.e. it interprets its
128-255 arguments as bytes rather than latin-1 chars).

I think so, yes.
