Create a string and parse a string to a standard set of characters

For order references it is important to not have any problems created by users mistyping information e.g. on a wiretransfer reference. Thus I looked at the characters of a european keyboard and tried to find all possible misinterpretations of letters either alone or as groups.

These are my findings of similiar looking characters:

o, O, Q, ö, Ö, 0
i, I, l, L, |, j, J, ı, 1
z, Z, 2
a, A, 4
s, S, 5
B, 8

g, q
q, 9
6, b
e, f
m, n
u, v


rn, m
vv, w

The final result should in my opinion only consist of Capital Letters and Numbers. Thus the list of letters to create a random string is the following:

CDEHKMPRSTUWXY012458

totaling 20 chars.

Installation

$ npm install distinguishable

Usage

var distinguishable = require('distinguishable');

Choose a different string length:

console.log(distinguishable.create(12));
// UXYYTHUMU8

Parse string:

console.log(distinguishable.parse("U4I1o00"));
// U411000

console.log(distinguishable.parse("UaILo0ö"));
// U411000
