	# The Average Overlap-of-Encoding Group Size is defined as follows:
	# 1. All characters that has the same encoding under an encoding scheme forms
	# an "Overlap-of-Encoding Group". From this we know that the number of
	# total OE groups of a certain encoding scheme is the same as the number
	# of total existing code under that scheme.
	# 2. The size of an OE group is defined to be the number of characters
	# within that group.
