Custom Character Table Registration screen
In the Tool menu, click Custom Character Table Registration to open the Custom Character Table Registration screen.
Create a custom character table on the Custom Character Table Registration screen. HULFT must be restarted in order to apply the registration of or any changes to a custom character table.
If you set Code Conversion Mode (codechangemode) to '1' in the System Environment Settings, HULFT treats output codes as variable-length codes and carries out conversion to custom characters.
However, if you register codes from the Custom Character Table Registration screen, you can only specify fixed-length codes for output codes.
To register output codes as variable-length codes, use the Custom Character Table Translate command (utlgtfextdV.exe).

Output
