Problem with diacritic sign.

[stMedard]

Hello, I like your library very much. I successfully matched it with the latest python and django. But I have a problem with Polish characters ąęśżźćółń. I had to replace the "basestring" on "str".

e_pub_ch = create_chapter_from_string(html_string="ąęśżźćóńł", url=None, title=i.title_chapter)
