single quote characters are stored as ' in the repository

To reproduce:

• create a new document
• enter some text, for instance "foo ' bar"
• save and close the document
• go the document in the console

Expected: the text is stored as "foo ' bar"
Actual: the text is stored as "foo ' bar"

I've reported the following bug in HtmlCleaner: https://sourceforge.net/p/htmlcleaner/bugs/154/

They are applying a different fix as part of https://sourceforge.net/p/htmlcleaner/bugs/118/ which also solves our issue.

For now, we're waiting for this issue to be addressed by the HtmlCleaner project.
