there will be 0x09 bytes in the character table (three bytes for each glyph) and four bytes in the header
section, the first entry in the table will be 13, or 0x00 0x0D in hexadecimal, and 0x05 for the width.
glyph, take the offset of the first entry and add the size of the first bitmap in bytes. Since the first glyph
occupies 0x05 bytes as seen in table 5.1.2 above, and the offset is 0x00 0x0D, the offset of the second entry
will be 0x00 0x12 and the width of the glyph is 0x03.

As you can see the letter h will take up five bytes with the last five bits being zero padded to form a full
The second part of the font file is the character table. The character table is comprised of three bytes for
The first two bytes represents the position, in bytes, of the glyph stored MSB LSB referenced from the
To calculate the second entry in the character table, representing the position and width of the second
Calculate the third entry the same way as the second to get table 9 below.
Once completed, place the character table after the header and the character data aat the end, as seen in
