thing is, I don't really mind where it is coded, but it already happens to
be in Parrot, kindof.
I can understand that it's not desired to PARROT_EXPORT a function as
described, and that's fine. However, that does mean I'll be duplicating
code.

PIRC absolutely needs this, and in that case it's absolutely safe to use, as
there is no encoding yet: I'm now converting the c-string into a STRING
(because that's what the unescaping function happens to return) , to then
convert it back into a c-string. Not useful. Not efficient.
