    $convmap     = array (
    int start_code1, int end_code1, int offset1, int mask1,
    int start_code2, int end_code2, int offset2, int mask2,
    ........
    int start_codeN, int end_codeN, int offsetN, int maskN );
    // Specify Unicode value for start_codeN and end_codeN
    // Add offsetN to value and take bit-wise 'AND' with maskN, then
    // it converts value to numeric string reference.
    ?>

    Example #2 mb_encode_numericentity() example

    <?php
    /* Convert Left side of ISO-8859-1 to HTML numeric character reference */
    $convmap = array(0x80, 0xff, 0, 0xff);
    $str = mb_encode_numericentity($str, $convmap, "ISO-8859-1");

    /* Convert user defined SJIS-win code in block 95-104 to numeric
    string reference */
    $convmap = array(

    To get Unicode numbers out of a UTF-8 string, this can be used, for example:

    <?php
    print mb_encode_numericentity ('sāш日', array (0x0, 0xffff, 0, 0xffff), 'UTF-8');
    ?>

    We were experiencing difficulties with PHP/Sablotron on Solaris; placing HTML character references into the XSL transformation, when set to output UTF-8, converts them back into UTF8 encoded chars. This was then a problem for non unicode storage. Using a bit of code from http://homepage.mac.com/marko/ the following function converts the string back to character references:

    function utf2html ($utf2html_string)
    {
    $f = 0xffff;
    $convmap = array(
    /* <!ENTITY % HTMLlat1 PUBLIC "-//W3C//ENTITIES Latin 1//EN//HTML">
    %HTMLlat1; */
    160, 255, 0, $f,
