Article doesn't mention yEnc, that is (or was?) very popular for binary attachments on usenet. from wikipedia https://en.wikipedia.org/wiki/YEnc https://en.wikipedia.org/wiki/YEnc > yEnc is a binary-to-text encoding scheme for transferring binary files in messages on Usenet or via e-mail. It reduces the overhead over previous US-ASCII-based encoding methods by using an 8-bit encoding method. yEnc's overhead is often (if each byte value appears approximately with the same frequency on average) as little as 1–2%, compared to 33–40% overhead for 6-bit encoding methods like uuencode and Base64.
