This commit removes the PYTHON_UTF8 workaround. The problem with setting

  LC_ALL= LANG=C LC_CTYPE=en_US.UTF-8

is that the en_US.UTF-8 locale might not be available. In this case
setting above locales results in build errors even though another UTF-8
locale was originally set [1]. The only stable way of fixing the
encoding problem is by explicitly annotating encoding/decoding in the
python script.
