#
#	General notes:
#
#	This table contains the data the Unicode Consortium has on how
#       ISO 8859-7:2003 characters map into Unicode.
#
#	ISO 8859-7:1987 is equivalent to ISO-IR-126, ELOT 928,
#	and ECMA 118. ISO 8859-7:2003 adds two currency signs
#	and one other character not in the earlier standard.
#
#	Format:  Three tab-separated columns
#		 Column #1 is the ISO 8859-7 code (in hex as 0xXX)
#		 Column #2 is the Unicode (in hex as 0xXXXX)
#		 Column #3 the Unicode name (follows a comment sign, '#')
