Using unicharadata module to help testing char alphabet.

Closes #215

Plus: I found some bad data structure, that i corrected. The tests are showing alphabet mistakes, that i leave for someone with more lang knowlege to solve. (and that is why checks will fail on travis)

Hey @aurium, thanks!

The code looks great, but it doesn't seem to be so accurate. I think it's because testing every single letter is not the best approach, because there are letters that being used in multiple alphabets.

For examplt:
AssertionError [ERR_ASSERTION]: The char "c" of "алекcaндр" is LATIN, expected to be CYRILLIC (lang rus).

Don't you think?

Hi @bluzi!
I don't know about char reuse. If you are sure about the same "c" is used on Latin and Cyrillic, i can update the alphabet test to accept it. There is more other special cases?

There is more other special cases in (Cyrillic==Latin)?
