We have a model driven application where we are using out of the box 'Export to PDF'. Our entity has 'Rich text attachment' columns. When we export the data using 'Export to PDF' button, all the special characters inside Rich text attachment columns are converted to html escape characters. Eg, if our column has value "Problem & resolution", then the PDF will show it as "Problem & resolution" It only happens with rich text columns. Plain text columns work fine
