Comment(by link92):

 The point of change_encoding in that case is to return a string that is
 guaranteed to be valid under that encoding. In the UTF-8 case, something
 like "\xff" is invalid, and should go through change_encoding and come out
 as whatever the UTF-8 encoding of U+FFFD is. This is needed for web compat
 with feeds. If there are bugs in the impl is change_encoding, they should
 be fixed.
