As soletan at toxa dot de reported, that function is very bad and does not provide valid enquoted printable strings. While using it I saw spam agents marking the emails as QP_EXCESS and sometimes the email client did not recognize the header at all; I really lost time :(. This is the new version (we use it in the Drake CMS core) that works seamlessly:

<?php

//L: note $encoding that is uppercase
//L: also your PHP installation must have ctype_alpha, otherwise write it yourself
function quoted_printable_encode($string, $encoding='UTF-8') {
// use this function with headers, not with the email body as it misses word wrapping
       $len = strlen($string);
       $result = '';
       $enc = false;
       for($i=0;$i<$len;++$i) {
        $c = $string[$i];
        if (ctype_alpha($c))
            $result.=$c;
        else if ($c==' ') {
            $result.='_';
            $enc = true;
        } else {
            $result.=sprintf("=%02X", ord($c));
            $enc = true;
        }
       }
       //L: so spam agents won't mark your email with QP_EXCESS
       if (!$enc) return $string;
       return '=?'.$encoding.'?q?'.$result.'?=';
}

I hope it helps ;)
