Re: PROPOSAL: i74: Encoding for non-ASCII headers

My reading is that HTTP is limited to iso-8859-1 *on the wire*, and  
requires RFC2047 encoding for characters outside of that range. Do you  
disagree with that?

My intent was not to disallow RFC2047, but rather to allow other  
encodings into iso-8859-1 where appropriate. Disallowing RFC2047 would  
be foolish and counter-productive; however, no one has said why  
constraining future headers from using other encodings than RFC2047 is  
a desirable -- or even realistic -- thing to do.

I'll follow up in more detail soon...
