- The MIME people worked hard to find an encoding that would survive *anywhere*
- in the known RFC822-mail universe. This is a lot harder than it looks, when
- you start thinking ugly thoughts like "Bitnet". Many of the non-alphanumeric
- ASCII characters are vulnerable to mangling in gateways. You can't beat six
- bits/character (i.e. 4/3 expansion) by much without using vulnerable
- characters.
