Users are supposed to control character encoding conversion if binary data is used for HTTP input/output. </p> <blockquote><p><b class="note">Note</b>: In PHP 4.3.2 or earlier versions, there was a limitation in this functionality that <i>mbstring</i> does not perform character encoding conversion in POST data if the <i>enctype</i> attribute in the <i>form</i> element is set to <i>multipart/form-data</i>. So you have to convert the incoming data by yourself in this case if necessary. <br /> Beginning with PHP 4.3.3, if <i>enctype</i> for HTML form is set to <i>multipart/form-data</i> and <i>mbstring.encoding_translation</i> is set to On in <var class="filename">php.ini</var> the POST'ed variables and the names of uploaded files will be converted to the internal character encoding as well. However, the conversion isn't applied to the query keys. <br /> </p></blockquote> <p class="para"> <ul class="itemizedlist"> <li class="listitem"> <span class="simpara"> HTTP Input </span> <p class="para"> There is no way to control HTTP input character conversion from a PHP script.
