The name of the algorithm for generating non-similar characters?

Question

Algorithms

Hello, can you tell me the name of the algorithm that generates a character string that does not contain visually similar characters? - I read about this about 5 years ago and I can’t remember how it’s called, or what the class of such algorithms is called.

Let me explain, there is a string

ABC O FG 0 As we can see the letters "O" and zero are visually similar, with manual typing this can cause problems The algorithm works so that visually similar letters will not fall into the string, that is, it
will turn out something like

ABCOFGZ

what is the name of this algorithm so I can google it?

Answer 1

you need alphanumeric without similar characters. e.g. DEC Alphabet:
A,B,C,D,E,F,H,J,K,L,M,N,P,R,S,T,U,V

Answer 2

When generating codes, an alphabet is used that is devoid of similar characters.
Both letters that look like numbers and numbers that look like letters are excluded.
For example: 3479BDFGHJKLMNPRSTWXZ
