There is no good standard practice, and this is why interoperability 
sucks for Content-Disposition.

The precise way to do it to make it explicit in the ABNF. Such as:

( "title" "=" quoted-string ) | ( "title*" "=" enc2231-string )

where

enc2231-string = <extended-value, see RFC 2231, Section 7>
