# This requires the Chilkat API to have been previously unlocked.
# 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..

# This ends the initial setup...

# 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.
