Thanks so much!! That is indeed the case! I now use strunvis and
it's all done in just 4 lines of code. (Well, except that I should
still handle a returned error code.)
int len = [stringA
lengthOfBytesUsingEncoding:NSUTF8StringEncoding];
char dst[len];
strunvis(&dst, [stringA UTF8String]);
return [NSString stringWithUTF8String:dst];
Not to burst your bubble, but that doesn't look quite right. It
fails in the case where stringA contains no escaped characters
(including the case where it's empty) -- the terminating null byte
isn't counted by lengthOfBytesUsingEncoding:, so it ends up writing
one byte off the end of dst[].
Ok, thanks for pointing that out. I'll just increase len by 1, that
way it should always fit.
