Alphanumeric mode does not work #43

Hi. When I try the alphanumeric mode, with any text (e.g. "here comes qr", it throws an error "Uncaught illegal char :h" in the console and no qr code is displayed. Is it a known issue and is going to be fixed?

Hi, The alphanumeric mode supports upper case only. https://en.wikipedia.org/wiki/QR_code
