Is it possible to add Alphanumeric string instead of binary data to make QR code? #177

Closed yo1995 closed 5 years ago

yo1995 commented 5 years ago

I've read from QR code's website and found that for each code, the capacities for different codeword set are not the same.

https://www.qrcode.com/en/about/version.html

For example, a version 2 code can have 47 alphanumeric characters, whereas only 32 binary bytes.

Therefore, I wonder if I can add alphanumeric characters, such as uppercase string to make a code instead of binary data? So that the code can hold a longer string within the same version number.

Thanks. 😄

Currently according to my test, this lib treat all data as binary ones, and follows the version capacity of binaries. If that is mistaken, please correct me.

Alright, it seems that I'm mistaken...it does treat alphanumeric as it is! never mind. 😅
