Doesn't support encoding of >26 characters

[danprince]

Been attempting to encode a URL of 30+ characters and when the generated QR is scanned, the data returned is empty.

QR's should definitely be able to store more than 26 characters.

QR code has different versions, that supports different amounts of data.

Please use the tables on this page to find a Version (and Error Correction Level) that suits your requirements...

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

...then specify them in the <qrcode> attributes, e.g. to get 4,296 alphanumeric characters, use:

version="40" error-correction-level="L"

Hope that works!
