TCPDF - PHP class for PDF

I didn't mean it as a true solution - just a quick work-around, either until Nicola decides to support the necessary CSS tags or something better comes up.

preg_match_all('|(<upper>)(.*?)(</upper>)|ims',$text,$matches);
for ($i=0;$i<count($matches[0]);++$i) {
$text = str_replace($matches[0][$i],strtoupper($matches[2][$i]),$text);
}

Something like that would be a quick-and-dirty work-around for you, I guess.
