Douglas Crockford documented his BASE32 encoding in 2002. It's a very friendly format with many nice characteristics, including those in Satoshi's base58 and more (listed in his "requirements" section here: https://www.crockford.com/wrmg/base32.html)

I like it, but I think the exclusion of U is unnecessary -- excluding Z2 or 5S similarities seems like it would be preferable.
