Is there a reason for this distinction between multibyte and unibyte?
I favour the "shotgun-approach" if not. It's bullet-proof.
The JavaScript function `encodeURIComponent()' encodes the German Umlaut
`ü' as `%C3%B6' regardless of the sources encoding actually. That's why
I wrote the two functions `org-protocol-unhex-string' and
`org-protocol-unhex-compound' (s. org-protocol.el).
I'll have to take a look at that RFC you mentioned :)
Best wishes
