# Get +str+ in Normalization Form KC.
#
# Normalization Form KC is compatibiliy decomposition (NFKD)
# followed by composition. Like NFKD, this normalization can alter
# how a string is displayed.
#
# Example:
#
# require "unicode_utils/nfkc"
# # LATIN SMALL LIGATURE FI => LATIN SMALL LETTER F, LATIN SMALL LETTER I
# UnicodeUtils.nfkc("fi") => "fi"
#
# See also: UnicodeUtils.compatibility_decomposition

str = UnicodeUtils.compatibility_decomposition(str)
