# Word Filter
# By rigbycwts
#
# Note:
# Starting on Gen 5, the main series games have a built-in word filter.
# The censor only prevents inputs in which exactly match the keyword. 
# However, previously, when trying to trade a Pokémon on the GTS, 
# the keyword only had to be contained in the name. This caused problems with 
# Pokémon whose names contained the keyword, such as Cofagrigus, 
# preventing them from being traded without nicknames, 
# so the filter was eventually removed. 
#
# However, the filter still prevents some Pokémon from being traded, 
# such as Nosepass.
#
# Algorithm:
# 1. Checks input text, creates a copy of it and converts it to uppercase.
# 2. If input text contains or matches the filtered word, 
#    it does not process the text, and returns to the text input screen.
# 3. If input text does not contain or match the filtered word,
#    the usual processing happens.
#===============================================================================

# Separate filters for Pokemon names, PC Boxes, Player names and Mail messages

# For Pokemon Names: Aside from the restriction above, a Pokemon can't be nicknamed
# with the name of another Pokemon. Example: You can't name a Typhlosion "Charizard."
