Address unicode issues in database

[dr-rodriguez]

When working with the database there are sometimes explicit representations of unicode characters (eg, \u2212) instead of what they should be (-). We need to investigate where this is happening; it is possible the input data is wrong (and thus a matter for the SIMPLE scripts) but we can probably force an encoding on the output JSON to ensure it doesn't happen on the file representation. The problem with having a mix of unicode characters is searching exact values can be much harder.

Basically, JSON is not meant to be human readable! So this behavour is expected!

If we want the JSON files to render the unicode, I think we can try this:

json.dumps(<text>, ensure_ascii=False)

Maybe we just add ,ensure_ascii = False) here. Not sure what will happen when it's read back in!
