Encoder/Decoder using a .ttf font for PUA (Private Use Area) Unicode characters.
A project just for fun. Maybe useful if you want to tranfer base64 encoded messages, so that procmail and friends have it a bit harder to filter messages.
Usage: $ base64 -w 20 < message.txt | pua -f pua.ttf > out.txt
Decode: $ pua -d -f pua.ttf < out.txt | base64 -d > message.txt
