Open mctrivia opened 8 years ago

mctrivia commented 8 years ago

QR Codes have 4 available character sets. To make smaller it should be checked if there are:

1) Only numbers 2) Alphanumeric: 0–9, A–Z (upper-case only), space, $, %, *, +, -, ., /, :

before falling back to binary option. https://en.wikipedia.org/wiki/QR_code#Storage
