# 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.
