You mean for hashes? Hm.. that's an interesting idea, which might get us
a whole new encoding. However, I don't quite think we can use Unicode
there, but should really stick to ASCII.

Even base64 is a bad idea, because it contains '/' and '+' chars, which
are usually treated as separators. But you don't want revision ids to
word-wrap.

With these restrictions, base58 is about as space efficient as you can get.

Kind Regards
