Issue Summary

Export doesn't work for assets that are returned by any AQL that contains the + icon. For example: Owner IN ("C+D Webworks")

Steps to Reproduce

1. Create an asset and set the value ("C+D Webworks") for a Select or Text type attribute for that
2. Export the assets returned from the above search, this will export an empty CSV file

Expected Results

The assets are exported as expected

Actual Results

The export process doesn't fail or show errors but the exported CSV file is empty

Workaround

Search with an AQL that doesn't contain the plus + icon. Search for that asset with some of it's other attributes.
