Hi,

I just noticed a problem in RFC 2231 that draft-reschke-rfc2231-in-http 
inherits:

    extended-initial-value := [charset] "'" [language] "'"
                              extended-other-values

Both charset and language can contain a single quote, so it's not the 
greatest choice as separator.

On the other hand, this doesn't seem to a problem in practice, so my 
plan for draft-reschke-rfc2231-in-http is to simply disallow single 
quotes inside charset and language.

Opinions?

BR, Julian
