Re: Thoughts on current discussion around QR codes

Yes, GB18030 is a Chinese national standard for encoding of Chinese characters.  Conceptually like JIS in Japan or ASCII or ISO-Latin-1 for other countries.

FYI: CHF118 is the standard price for most ISO standards.
Remember that ISO makes its $$ selling their standards while allowing *free* membership in their standards process (vs. the W3C that *charges* for membership, but makes their standards free).   Everyone has to make a living and both approaches towards standards development are valid.

Han Xin is a 2D bar code symbology intended particularly for the representation of Chinese characters.
