// Why base-58 instead of standard base-64 encoding?
|
|
// - Don't want 0OIl characters that look the same in some fonts and
|
|
// could be used to create visually identical looking account numbers.
|
|
// - A string with non-alphanumeric characters is not as easily accepted as an account number.
|
|
// - E-mail usually won't line-break if there's no punctuation to break at.
|
|
// - Doubleclicking selects the whole number as one word if it's all alphanumeric.
