QRCode default encoding, ISO-8859-1 (Latin 1), has no support for CJK characters. I modified the code so as to use UTF-8 encoding in case characters outside Latin1 set are present in the barcode string. However be aware that support for characters outside Latin1 set is not uniform across barcode readers and barcode apps, sometime it is necessary to modify settings in order to get UTF-8 support, sometime UTF-8 is not supported at all. So I'm not quite sure it is a good idea to use CJK characters in your QR codes.
