Improve handling of encoding errors in CSS #149

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
The following epub encodes its CSS in Latin 1 such that it can't be
automatically re-encoded in UTF-8. Bookworm doesn't need to handle this but
it should provide a better error, especially since epubcheck passes it.

The OPF/OPS specs seem ambiguous on what encoding included CSS files MUST be 
in, I
don't think it's unreasonable that EPUB creators use UTF8 for everything. If 
you'd
like to try to do something with Latin1, you may be interested in

>>> import chardet
>>> crazy_css = open('taz_ebook.css')
>>> chardet.detect(crazy_css.read())

A similar problem happens if the NCX isn't in UTF-8 (Bookworm barfs 
gracelessly).
