i am using pay per word perk first time... Can we customize this this plugin to pay per character?

@mohitit I'm not sure why I never thought of it, but yes, this can easily be modified to support paying per character. New snippet here: https://gist.github.com/spivurno/bf3b4a944b307d8ec57e29f77cd0ac91
