Yes, now it is clear.

no, 'print s' prodices error:
'UnicodeError: ASCII encoding error: ordinal not in range(128)'

now, values are not listed in the link you gave me

>>> txt =3D "=C1=C2=D7"
>>> type(txt)
<type 'string'>
>>> txt.decode("koi8-r")
Traceback (most recent call last):

and dir(txt) doesn't contain attribute 'decode'

no, I can't see anything reasonable:

>>> u =3D u'\u042F\u042B\u042C'
>>> u
u'\u042f\u042b\u042c'
>>> print u

Traceback (most recent call last):
  File "<stdin>", line 1, in ?
UnicodeError: ASCII encoding error: ordinal not in range(128)

sorry, I still can't understand source of my problems :(
