Again, RFC 3987 would require that

  @charset "iso-8859-1";
  element { background-image: url(Bjo\000308rn) }

yields in a request for Bj%C3%B6rn and that

  @charset "utf-8";
  element { background-image: url(Bjo\000308rn) }

yields in a request for Bjo%CC%88rn.

Both are "UTF-8" but differ in their Unicode Normalization. Some CSS
implementations do the latter but few if any implementations do the
former which is not surprising as that would be inconsistent with a
number of specifications.
