 Nope, that's incorrect. Note how the & and = in the query string have been
 encoded. That was issue 112, which was fixed. This appears to be a new
 issue, but related.

 This appears to be related to
 https://github.com/simplepie/simplepie/issues/162 and possibly
 https://github.com/simplepie/simplepie/issues/58

 From the issue description:

 {{{
 http://news.google.com/news?gl=vn&pz=1&cf=all&ned=vi_vn&hl=vi&q=ch%E1%BB%91ng+h%C3%A0ng+gi%E1%BA%A3&output=rss
 http://news.google.com/news?gl=vn&pz=1&ned=vi_vn&hl=vi&q=ch%EF%BF%BD%EF%BF%BD%EF%BF%BDng+h%EF%BF%BD%EF%BF%BDng+gi%EF%BF%BD%EF%BF%BD%EF%BF%BD
 }}}

 Note that `&cf=all` and `&output=rss` have disappeared. All the characters
 in the original URL have been turned into a � character (U+FFFD, aka 0xEF
 0xBF 0xBD). That would indicate to me a possible issue with iconv or
 mbstring on the version of PHP on the server. I'll have a dig into this
 when I've got stable internet.
