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,
/* <!ENTITY % HTMLsymbol PUBLIC "-//W3C//ENTITIES Symbols//EN//HTML">
    %HTMLsymbol; */
