+#	Name:             GSM 03.38 to Unicode
+#	Unicode version:  3.0
+#	Table version:    2.0
+#	Table format:     Format A
+#	Date:             2009 Nov 10 (header updated: 2015 December 02)
+#	Authors:          Ken Whistler
+#                         Kent Karlsson
+#                         Markus Kuhn
+#
+#	General notes:
+#
+#	This table contains the data the Unicode Consortium has on how
+#       ETSI GSM 03.38 7-bit default alphabet characters map into Unicode.
+#	This mapping is based on ETSI TS 100 900 V7.2.0 (1999-07), with
+#	a correction of 0x09 to *small* c-cedilla, instead of *capital*
+#	C-cedilla.
+#
+#	Format:  Three tab-separated columns
+#		 Column #1 is the ETSI GSM 03.38 7-bit default alphabet 
+#                             code (in hex as 0xXX, or 0xXXXX for double-byte
+#                             sequences)
+#		 Column #2 is the Unicode scalar value (in hex as 0xXXXX)
+#		 Column #3 the Unicode name (follows a comment sign, '#')
+#
+#	The entries are in ETSI GSM 03.38 7-bit default alphabet code order.
+#
+#       Note that ETSI GSM 03.38 also allows for the use of UCS-2 (UTF-16
+#       restricted to the BMP) in GSM/SMS messages.
+#
+#	Note also that there are commented Greek mappings for some 
+#	capital Latin characters. This follows from the clear intent
+#	of the ETSI GSM 03.38 to have glyph coverage for the uppercase
+#	Greek alphabet by reusing Latin letters that have the same 
+#	form as an uppercase Greek letter. Conversion implementations 
+#	should be aware of this fact.
+#
+#       The ETSI GSM 03.38 specification shows an uppercase C-cedilla
+#       glyph at 0x09. This may be the result of limited display
+#       capabilities for handling characters with descenders. However, the
+#       language coverage intent is clearly for the lowercase c-cedilla, as shown
+#       in the mapping below. The mapping for uppercase C-cedilla is shown
+#       in a commented line in the mapping table.
+#
+#	The ESC character 0x1B is
+#	mapped to the no-break space character, unless it is part of a
+#	valid ESC sequence, to facilitate round-trip compatibility in
+#	the presence of unknown ESC sequences.
+#
+#	0x00 is NULL (when followed only by 0x00 up to the
+#	end of (fixed byte length) message, possibly also up to
+#	FORM FEED.  But 0x00 is also the code for COMMERCIAL AT
+#	when some other character (CARRIAGE RETURN if nothing else)
+#	comes after the 0x00.
+#
+#	Version history
+#	1.0 version: first creation
+#	1.1 version: fixed problem with the wrong line being a comment,
+#			added text regarding 0x00's interpretation,
+#                       added second mapping for C-cedilla,
+#                       added mapping of 0x1B escape to NBSP for display.
+#   1.2 version: fixed fallback mapping for 0x03A5.
+#
+#   2.0 version: updates to copyright notice and terms of use; no
+#       changes to character mappings
