Appendix A: wrong example statement using bookmarklet

 Note: f71cfdc6a5b4ca823f13f2b7e5be6677d112084e could start a discussion about adopting the UTF-8 encoding for xAPI. Not sure if really required: [RFC 4627](http://tools.ietf.org/html/rfc4627#section-3) is IMHO clear enough in describing the discovering of the used encoding for the JSON payload.
