A while ago I wanted to pack as much information as
possible into a string of printable characters, and
I came up with a base-95 encoding that packs 9 bytes
into 11 characters.

The application involved representing data using
Python string literals, so it was important that only
printable characters were used. I settled on the
9/11 combination as a reasonable compromise between
packing efficiency and not having the block size
too long.

If anyone's interested, I could dig out the
encoding and decoding routines I wrote.
