Ah got it! Thanks a bunch.

Thanks for ABE. I've been trying it out with a few different alt-coins. I could do with a hand understanding address_version.

For most coins it seems to be obvious, just the unicode of the first character of an address. But some coins have addresses like this (feathercoin in this example)

6nh62XDjhbqjjit78jfStECNcHz89xbNeq
72HzQ77Xbpg67MadosyWDjd5YZsVHz4Npt

etc...

I've tried settings an address_version of "\u0036" (a unicode '6') and this seems to work fine, however I'm worried that is not right. Is \u0036 ok, or should I do something else?
