# These additional emoji are not in the definition file, but are useful in conjunction with it

# This is a combinin character that can be placed after any other character to surround
# it in a "keycap" symbol.
# The digits 0-9 are already in the emoji table as keycap_digit_<N>, keycap_ten, etc. 
# It's unclear whether this should be in the $emoji array, because those characters are all ones
# which can be displayed on their own.
