3	Q	Approx 55% of symbol	Approx 25%
4	H	Approx 65% of symbol	Approx 30%

The maximum capacity of a (version 40) QR Code symbol is 7089 numeric digits, 4296 alphanumeric characters, or 2953 bytes of data. QR Code symbols can also be used to encode GS1 data. QR Code symbols can encode characters in the Latin-1 set and Kanji characters, which are members of the Shift-JIS encoding scheme. Input should be entered as a UTF-8 stream, with conversion to Shift-JIS being carried out automatically by Zint. A separate symbology ID can be used to encode Health Industry Barcode (HIBC) data, which adds a leading '+' character and a modulo-49 check digit to the encoded data.
