Why not embrace the Unicode world we live in now and just offset bytes to a Unicode region that has 256 non-space characters?

Pros: simple, no ratio or ending calculation, easy copy/paste, same character length as original bytes

Cons: has to be percent encoded in urls, some fonts might not render all characters

In utf8, these characters are all encoded as two bytes. So this encoding makes the byte count twice as long, it's no more efficient (in bytes) than hex encoding.
