RFC2396 [URI] states:

	"Internet protocols that
   transmit octet sequences intended to represent character sequences
   are expected to provide some way of identifying the charset used, if
   there might be more than one [RFC2277].  However, there is currently
   no provision within the generic URI syntax to accomplish this
   identification. An individual URI scheme may require a single
   charset, define a default charset, or provide a way to indicate the
   charset used."

but RFC3261 [SIP] appears to do none of the above.
