    //  This initial setup, which involves setting the OAuth1 properties and connecting
    //  to api.twitter.com, is only required once at the beginning.  Once connected, the same
    //  object instance may be re-used, and if necessary, it will automatically reconnect
    //  as needed.

    //  For this example, I've pre-created a text file containing two emoji
    //  characters (the "ghost" emoji, and a "face savouring delicious food" emoji).  
    //  This text file was saved using the utf-8 encoding.

    //  The utf-8 bytes for the ghost emoji are 0x9f 0x91 0xbb.  (Note: This is the utf-8
    //  representation that does not use surrogate pairs.)
