Unrelated, but this links to "Crockford's alphabet", https://www.crockford.com/base32.html , which is a base-32 system that includes all alphanumeric characters except I and L (which are confusable with 1), O (which is confusable with 0), and U (????). The page says the reason for excluding U is "accidental obscenity'. What the heck is it talking about?
