hprotagonist on Print off a QR code for guests to join your WiFi network

the little DSL format looks like this:

  WIFI:S:NETWORK-NAME;T:WEP;P:NETWORK-PASSWORD;H:false;;

and i use the python tool `qr` to generate one: https://pypi.org/project/qrcode/

The key/value pairs after the "WIFI:" prefix are as follows:

  S - the SSID
  P - the password
  T - the encryption type (WEP, WPA, or blank)
  H - whether or not it's a hidden network

The only required pair is "S"; all other pairs are optional and may be omitted if desired.

Is this format specified somewhere? How do you escape the separation characters if used in one of the keys?
