mojibake is a script to "mojibake"-ify binary data so that it can be copy/pasted between (unicode-aware) terminals
The base64 format was designed to encode binary data within a set of characters that were safe for (text-only) e-mail. It was designed to be reasonably efficient -- each 8-bit base64 character can represent 6 bits of binary data. Or, 4 base64 characters represent 3 bytes of binary data.
Instead of optimizing for an efficient size transformations, what if you optimize for how many bytes you can represent in each character? Unicode has over 2^16 assigned characters, so you could represent two bytes per character!
It's not very space efficient, though. Those two bytes of binary data need 4-5 UTF-8 bytes to encode them as a unicode character.
But it looks cool!

When I'm ssh-hopping around on machines, sometimes I just want to copy-paste a couple small script files somewhere. Sometimes I use tar cz foo bar | base64 to grab them. But it's even easier with mojibake:
$ mojibake foo bar

Then, on my destination machine:
$ mojibake --unzip
Paste the mojibaked zip file. Type '.' to finish.

If you want to see the cool chinese characters instead of a screen full of boxes, you'll need to install fonts that support the unicode CJK Unified Ideographs Extension B. You may already have a font that can handle these characters. If not, I recommend the freely available Hanazono.
