[TBA]: TBA API 2011 data

I was working on a project and noticed that none of the 2011 data is populated yet. Is there any estimate of when this data will begin populating? Is the API still supported?

Also, a small issue keeps popping up, I am calling the get_teams function to load all of the teams. Loading the page that it actually navigates to in Chrome keeps giving me a warning

This page contains the following errors:

error on line 2 at column 1015324: Encoding error
Below is a rendering of the page up to the first error.

I also get an error complaining about encoding of the data in the code that I was using the parse this data. Is the encoding set properly in the xml?
