Comment:

 Thanks for the extra information.  I can reproduce this with the code
 below:

 {{{
 $url =
 'https://news.google.com/news/feeds?gl=vn&pz=1&cf=all&ned=vi_vn&hl=vi&q=ch%E1%BB%91ng+h%C3%A0ng+gi%E1%BA%A3&output=rss';
 var_dump($url);

 // outputs:
 // string
 'https://news.google.com/news/feeds?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'
 (length=117)

 $iri =& new SimplePie_IRI($url);
 var_dump($iri->get_iri());

 // outputs:
 // string
 'https://news.google.com/news/feeds?gl=vn&pz=1&cf=all&ned=vi_vn&hl=vi&q=chống+hàng+giả&output=rss'
 (length=101)
 }}}

 The problem is happening in
 `SimplePie_IRI::replace_invalid_with_pct_encoding()`.
