QRcode printing with unicode characters

Hi,

We're trying to print out QRcode in smartforms by referencing below link with output device ZBWIPP and device type ZBWIPPQR.

http://www.rjruss.info/2010/09/how-to-printpdf-qr-codes-in-standard.html

Meanwhile, we need to print out trad. Chinese in same smartform.

Seems that QRcode and trad. Chinese are in different character set.

Would there be any device type which supports QRcode and unicode ?

or any revision requires for ZBWIPPQR device type?

Please help.

Thank you.
