Check to make sure that unicode characters are converted within fields

E.g., some html characters are appearing as not rendered within the description / abstract field -- issue related to what has come over from drupal treatment of these characters.

No files or tests are named. Start by reproducing the issue with HTML or Unicode characters in the description and abstract fields, then trace how data from Drupal is handled by the API. Done means those characters are converted and rendered correctly in both fields.
