Fixes test-encoding for python2.3 and minor cleanups: - Use koi8-r instead of euc-jp, as the later isn't available in python2.3. - Add unicode representation for latin1 e', too. - Use date "1000000 0" like in other tests (though not strictly needed because we no longer use %c as default datestr format).
