Exclude similar looking characters

[karentamrazyan]

Some characters are looking very similar to the other one, so that it's sometimes difficult to distinguish them.
A great example is the capital letter "O", which looks very similar to the character/number "0" (zero).
We want to provide a feature to avoid this kind of characters from the generated password.

Here are further characters:

• 0 (number zero)
• O (capital o)
• 1 (number one)
• l (small l)
• ...

Why don't we make a library of characters that exclude those hard to identify ones? I dont know the details of the crypto API but if it provides an array of letters/ numbers we could splice them out

Good point @JKHunter315! Started this wiki page Similar Characters to collect all "similar" characters in one place.
