Add X52 character mapping configuration file

This file is parsed during compilation time to generate a static lookup
table which is used to convert UTF-8 text to a character supported by
the X52 MFD.

+# Conversion Map for X52 Pro MFD character map
+# The X52 Pro MFD uses a single byte character set and encodes multiple
+# character ranges in that set. This file defines the mapping from Unicode
+# code points to the vendor character set. This is transformed at compilation
+# time to a lookup table using UTF-8. All characters must be explicitly
+# specified to be added to the lookup table.
+
+# Lines must be formatted as follows
+# <Unicode Code point in hex> <MFD Charmap value in hex>
+# or
+# <Unicode Code point in hex> <MFD Charmap value as single character>
+# Comment lines begin with the # character in the first column
+# Comments may begin after the character map value, they are ignored as long
+# as the rest of the line is in a valid format.
+
+# Code points which are not found in the list below will translate to
+# 0xDB which is the entry in the character map for a box (similar to U+25FB)
+
+# Note that the library will not attempt to perform any additional matching
+# steps like iconv does to find a close match in the glyph, so if you need
+# to add any such "close matches", you will need to explicitly list them
+# in the list below.
+
+# Printable ASCII Range - These map directly onto their respective code points
+# except where specified.
