This screen will be seldom used since the default characters are the numbers 1-9 for a 9X9 geometry and a hexadecimal set for anything larger. If you need extra complexity you can use different characters using this screen.
Any characters can be used as long as they are single Unicode characters (addressable by a 4 digit hexadecimal number). Values can be any strictly positive integers but must be entered in ascending sequence. A check is made to ensure no duplication of the Unicode number but this does not guarantee that the character is not duplicated, for example, the character B can be 0042 – Latin capital b, 0392 – Greek capital beta, 0412 – Russian capital v.
