Non-breaking space named entities in manuscript content cause an export error
When a manuscript's content contains non-breaking spaces encoded as , Pressroom throws an error exporting to PDF or DOCX (at least).
This could either be fixed at the Pressroom side, perhaps by providing an XHTML doctype that defines the named entities when parsing the XHTML, or in the client by ensuring that numeric entities are used instead of named entities when serializing to XHTML.
