The easiest way is probably just to use repr/eval, like this:

Python 2.3.4 (#1, Jun  4 2004, 19:45:32)
[GCC 2.95.3 20010315 (release)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> repr("az állam én vagyok")
"'az \\xe1llam \\xe9n vagyok'"
>>> print repr("az állam én vagyok")
'az \xe1llam \xe9n vagyok'
>>> eval("'az \\xe1llam \\xe9n vagyok'")
'az \xe1llam \xe9n vagyok'
>>> print eval("'az \\xe1llam \\xe9n vagyok'")
az állam én vagyok

Not that repr() puts a set of '' around the string and eval() needs these in
order to 'parse' the string.

Hope this helps!
