Encoding in Alphanumeric encoding (11 bits per 2 characters)

[jesslly]

I tried creating a qr code with case sensitive = 0 and 8 bit encoding = 0.

Somehow the program still encoding the information in 8 bit mode.

If I put hint = QR_MODE_AN, it throws out an error. It's throwing an error because the hint is not QR_MODE_8bit.

Can someone give me the required steps to always encode in alphanumeric?

thanks,

If a given string contains a character that cannot be encoded in AlphaNumeric mode, libqrencode uses 8 bit mode to encode it. QR code's AlphaNumeric character set contains alphabets, numbers, a space character and some symbols (%*+-./:). Please check your data.
