Grrr.
It's related to recent problem with cp0.

Searching in google I found that cp720 is arabic OEM codepage.
Codec for this codepage is absent in standard python.

I found emacs-lisp script that related to this:
http://www.koders.com/lisp/fidDBF4E46FB3572478847661772FA06F779BF04A15.aspx
but I don't know is it possible to write corresponding
encoding table to extend python's standard set of codecs.
(I don't know el scripting language).

So we need to be a paranoid about encoding and explicitly check
that python could handle this correctly.

I'll prepare my full paranoid patch.
