@bic to make sure which version of Python you are running: import sys print(sys.version) in SublimeText3 you can set the Python version in Tools > Build System. handling of unicode changed radically from py2 to py3. see: Strings, Bytes, and Unicode in Python 2 and 3 Unicode strings in Python: A basic tutorial hope this helps!

But just to be clear: we're not going to bundle py3 modules with the py2 DB build.
