RFC 2231 defines extensions to RFC 2183 disposition parameter
value mechanisms to provide value character set information
(http://greenbytes.de/tech/webdav/rfc2231.html#rfc.section.4),
e.g.:
Content-Disposition: attachment; filename*=UTF-8''foo-%c3%a4-%e2%82%ac.html
The following pattern detects the cases described in
http://greenbytes.de/tech/tc2231/#encoding-2231-char
(RFC2231 Encoding: Character Sets).
TODO: The value of filename ($2) must be decoded according to
the encoding specified in $1.
