According to the Wikipedia article on QR codes, "The information encoded
can be made up of four standardized kinds ("modes") of data (numeric,
alphanumeric, byte/binary, Kanji), or through supported extensions,
virtually any kind of data." The article explains the four modes as
follows:
• Numeric encoding (10 bits per 3 digits)
• Alphanumeric encoding (11 bits per 2 characters)
• Byte encoding (8 bits per character)
• Kanji encoding (13 bits per character)
The "byte" mode, together with a byte-based Unicode encoding scheme like
UTF-8 or even (shh!) SCSU, could theoretically encode a sequence of
arbitrary Unicode characters. The article doesn't say what a "supported"
extension is, but I'm sure more complete references are available.
