original file is libiconv-1.14/tests/BIG5-HKSCS-2008.TXT. All mappings of
pure BIG5 are removed.
Change four composed characters's 2 unicodes to 1

the mapping is from e_hkscs_2008.pdf:

take 88A5 for example:

88a5 <00ea 030c> f346 f346

use ftdump to search u+xxxx->glyph index

0xf346 => 23278

23278's glyph is right!
mv g*.[ch] to graph/
Format the mapping to be included in .c
write matrix mapping like cp932 for new added 5009 chars of HKSCS-2008

The mapping is HKSCS-2008 BIG5 encoding --> uTF-8
ignore font files
