This parser is very simple and doesn't do any error checking or validation. It
requires the using System.IO statement to allow text files to be read from the
disk. Each CharacterData structure is filled up and then its Id is cast to a
character to use as the index. The Id is the ASCII number representing
the character; casting the number to C#'s char type will convert it to the correct
character.
