Style MSB (UI)
The Style MSB (byte 4) is combined with the Style LSB (byte 23) to
make the style word. The contents of the style word are described
below. The Style word (decimal) is calculated using the formula:
Style Word = Posture + (4 x Width) + (32 x Structure)
The binary structure of the Style word is shown below.
2 Bound font. All character codes 0 to 255 are
