A font-glyph block makes it possible to provide sprites for glyphs that don't have sprites in normal TTD. The syntax is as follows:
font_glyph (<font-size>, <base-char>, <image-file>) {
list of realsprites
}
The first parameter (<font-size>) should be an identifier of the font size to use. Valid values are SMALL, NORMAL, LARGE and MONO.
The second parameter (<base-char>) is the number corresponding to the first character to provide a sprite for. Valid values are all unicode code points in the Basic Multilingual Plane (0-0xFFFF)
Parameter three <image-file> is a literal (quoted) string that specifies the file where the sprites are located.
<real-sprites> should be a list of real sprites. The first real sprite will be used for the character with code base-char;, the second for base-char + 1 and so on. These sprites should only use colour palette indices 0 (transparent), 1 (foreground), and 2 (shadow).
