minimum version for the given input data.

error correction level (<code>0</code> - <code>3</code>, lowest to highest)

level

tell the library how Japanese Kanji characters should be
encoded. If "<code>3</code>", the library assumes that the
given string contains Shift-JIS characters and encodes them in
Kanji-mode. If "<code>2</code>" is given, all of non-alphanumerical
characters will be encoded as is. If you want to embed UTF-8
string, choose this. Other mode will cause EINVAL error.
"<code>0</code>" is "numeric mode", "<code>1</code>" is "alphanumeric mode",
"<code>5</code>" is "ECI mode".

hint

case-sensitive(<code>1</code>) or not(<code>0</code>).

Quick Response codes (QR codes) are a type of matrix bar code and can be
used to authenticate transactions, provide access to multi-factor authentication
services and enable general data transfer in an image. QR codes use four standardized
encoding modes (numeric, alphanumeric, byte/binary, and kanji) to efficiently store
data. Matrix barcode generation is performed efficiently in C via the included
'libqrencoder' library created by Kentaro Fukuchi.
