This is incomplete.
Stores images of characters used to display text. Can be found in Mario Kart Wii and possibly others.
The file structure is composed by a header and sections. There always appears to be a FINF, TGLP and CWDH section along with one or more CMAP sections.
The file is not completely known.
The endianess is Big Endian.

0008: DWORD length of whole file
000C: WORD ??
000E: WORD ?? (language flag?)
FINF Header 20H bytes:

TGLP Data Bitmap is formed in a Zig-zag way.
A single block of bitmap looks like this:
00 01 02 03 04 05 06 07
08 09 0A 0B 0C 0D 0E 0F
10 11 12 13 14 15 16 17
18 19 1A 1B 1C 1D 1E 1F
Multiple blocks:
B01 B02 B03 ... B08 (assume width=64)
B09 B0A B0B ...
...
Multiple images:
I01
I02
I03
...
