# reads the file and returns a list of mappings required to remove all
# diacritical marks from a unicode string. Each mapping is itself a list
# consisting of two elements - the unicode codepoint and the single ASCII
# character that it should be replaced with, or an empty string if the 
# codepoint should simply be removed from the input. Examples:
#
#   { 224 a  }     (replace codepoint 224 to "a")
#   { 769 "" }     (remove codepoint 769 from input)
#
# Mappings are only returned for non-upper case codepoints. It is assumed
# that the input has already been folded to lower case.
