This function converts the string <code class="parameter">data</code> from the
<em>UTF-8</em> encoding to <em>ISO-8859-1</em>. Bytes
in the string which are not valid <em>UTF-8</em>, and
<em>UTF-8</em> characters which do not exist in
<em>ISO-8859-1</em> (that is, characters above
<em>U+00FF</em>) are replaced with <em>?</em>.
</p>
<blockquote class="note"><p><strong class="note">Note</strong>:
<p class="para">
Many web pages marked as using the <em>ISO-8859-1</em> character
encoding actually use the similar <em>Windows-1252</em> encoding,
and web browsers will interpret <em>ISO-8859-1</em> web pages as
<em>Windows-1252</em>. <em>Windows-1252</em> features
additional printable characters, such as the Euro sign
(<em>€</em>) and curly quotes (<em>“</em>
<em>”</em>), instead of certain <em>ISO-8859-1</em>
control characters. This function will not convert such
<em>Windows-1252</em> characters correctly. Use a different
function if <em>Windows-1252</em> conversion is required.
