I'm also going to attempt to attribute the sources to given countries or at least language families. The list as it stands has a heavily US-centric bias.

I plan to grep through it and pull out things like Cyrillic or Arabic characters, and then repeat the process using only those characters. That's not to say that everyone who uses Arabic or Cyrillic characters is guaranteed to use them, but it's more specific.

If "password" is #2 in the world, perhaps пароль (password) will be the #2 most popular password with Russian Cyrillic Characters

There should be libraries in any language used to develop systems which validate user-entered passwords.
