Description:
------------

From manual page: http://www.php.net/class.imagick
---
$im = new Imagick();
$svg = '<?xml version="1.0" encoding="UTF-8"?>';
$svg .= '<svg style="width:240; height:240;" version="1.1">';
$svg .= svg_figure();
$svg .= '</svg>';

$im->readImageBlob ($svg);
$im->setImageFormat ($_REQUEST['type']);
$im->paintTransparentImage ($im->getImagePixelColor (0, 0), 0, 0);
echo $im;

function svg_figure($char){
return '<svg>
<text id="letter" x="5" y="14"><tspan style="font-family:Arial, Helvetica, sans-serif; font-size:20pt;" >'.chr($char).'</tspan></text>
</svg>';
}

I run (code are just relevant sniplets) svg_figure() through various aasci-codes. All (printable) characters are printed fine except "<" and "&".

from what I can tell, you are generating invalid xml.
either use CDATA or htmlspecialchars if you want to put arbitrary strings into your svg xml.
