InaSAFE Disaster risk assessment tool by AusAid -**Internationalisation
utilities.**

The module provides utilities function to convert between unicode and byte
string for Python 2.x. When we move to Python 3, this module and its usage
should be removed as string in Python 3 is already stored in unicode.
