<ul class="simple">
<li>don’t try <tt class="docutils literal"><span class="pre">iso-8859-1</span></tt> (can’t distinguish between <tt class="docutils literal"><span class="pre">iso-8859-1</span></tt> and <tt class="docutils literal"><span class="pre">windows-1252</span></tt> anyway, and most incorrectly marked feeds are <tt class="docutils literal"><span class="pre">windows-1252</span></tt>)</li>
