<para>
According to the <ulink url="http://www.w3.org/TR/REC-html40/interact/forms.html#adef-accept-charset">HTML 4.01 specification</ulink>,
Web browsers are allowed to encode a form being submitted with a character
encoding different from the one used for the page.
See <function>mb_http_input</function> to detect character encoding
used by browsers.
</para>
<para>
Although popular browsers are capable of giving a reasonably accurate guess
to the character encoding of a given HTML document, it would be better to
set the <literal>charset</literal> parameter in the
<literal>Content-Type</literal> HTTP header to the appropriate value by
<function>header</function> or
<link linkend="ini.sect.data-handling">default_charset</link> ini setting.
