Creating Custom Character Sets for File Conversion

The custom character sets are stored in standard ASCII files as conversion tables. Each original character and the character to which it is translated are defined by a single line in the file. The line number of the file itself indicates the decimal code value of the original character.

The character conversion table must be the only contents of the conversion file. Do not insert any comments or additional numbers. Each conversion file must contain 256 lines. If your text editor or word processor provides a line counter, you can use it to help you keep track of the line numbers. The procedures and examples below assume that the editor's line counter begins at 1.
