Please add a note if this is intentional. 78245 1 pub-w3 2012-11-12 22:11:24 +0000 As far as I can tell, Safari and Firefox, the ones that map from 0x80--0xFF to U+F780--U+F7FF, also map back to %80--%FF for form submission as expected. 78246 2 annevk 2012-11-12 22:42:36 +0000 Oh really? So it could just be defined as a single-byte encoding?
