1. cjklib ('cjklib' on pypi) is a pure-python swiss-army knife translation library for character-oriented languages like Chinese.
2. WebOb ('webob' on pypi) is a popular python WSGI middleware library for building reusable python web applications.

I've tested both of these in my buildozer-created APK and they work great. No patches required as they do not have C-extensions.

One warning: cjklib uses sqlite and creates a pretty "hefty" 45 MB database upon it's 'setup.py' installation for the purposes
of translating different languages. I've submitted a request on their mailing list for options for pruning the size of this
database. Hope to get a response from them soon.
