Which encoding would allow you to transmit binary data over an ASCII-only communications channel?

EXPLANATION

Base64 is a format that encodes arbitrary binary data into ASCII characters (letters, digits and limited punctuation).  These characters then can be decoded back into binary at the other end.  This allows transmitting binary data over channels that normally only allow ASCII (such as email or display terminals).  Base64 takes up 1/3 more space than the equivalent binary format.
