Code128 not recording '|' character properly

[aranar-pro]

Code 128 Barcode generated if code contains a '|' character (&#124) does not scan correctly. The codes are visibly different from the same code put in other barcode generators. Scanning the code delivers a code missing the '|' character. Possibly an illegal or unescaped character issue.

in Code128.php changing:
else if(strtoupper($this->data) == $this->data)
to
else if((strtoupper($this->data) == $this->data) && (!preg_match("/|/", $this->data)))
fixes the problem.
