edit/create posts not possible (encoding)

looks like a encoding problem, probably the same exception on #434635

AttributeError: BloGTK instance has no attribute 'timeout_handler_id'

solution idee: set the default to UTF-8 and lang en with the ability to change in the Blogtk Settings Manager.

- gentoo linux system with python 2.6

FYI:
On start a deprecated modul information but it is not the reason for the post exception:

/usr/lib64/python2.6/site-packages/gdata/tlslite/utils/cryptomath.py:9: DeprecationWarning: the sha module is deprecated; use the hashlib module instead
  import sha
