Character range

Description
The character range is the range of characters that can be used in a font. For example, a game may only use numbers, and to save time, a game designer would change the character range so that it only numeric characters are included in the font. Every character, including letters, numbers and icons, is given a unique number between 0 and 255. Since most games don't use every available character, only the basic characters (32 till 127) are included by default. If a game requires all characters, the character range must be changed to '0 till 255', and if the game requires only digits, the character range used would be '48 till 57'.
