// See Global Unlock Sample for sample code.

// 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.

// Assume we've previously obtained an access token and saved it to a JSON file..
// For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.JsonObject')
$json = new COM("Chilkat.JsonObject");

// 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.)
// 
// The utf-8 bytes for the "face savouring delicious food" emoji are \xF0\x9F\x98\x8B.

// For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.StringBuilder')
