You keep making it sound like it's hard because you need to know them all to do "conversion".  Typically you wouldn't.  Treat them as opaque strings unless you have some real need to know them.  You may want to parse them, to make sure they're well formed, but if you already did that on reception then you don't need to do it again either.
