During our test porting an existing application that uses iTextSharp to Mono we
found out that creating a PDF file from HTML (using the ParseXHtml method from
the class XMLWorkerHelper) fails. We debugged our software first but the source
of the error was during the registration of the path of the fonts
(core/iTextSharp/text/FontFactoryImp.cs). One of my colleagues used your
library with Mono so we reviewed the changes to that particular file and
discovered that one change was made to the file (quite a while ago to be
honest, in 2010) that changed the behavior of the library on Mono (mainly
because of how Mono handles the special folders that cannot be mapped directly
to the Linux equivalent). We made a patch for it (the one I'm sending with this
e-mail, a diff between the version of the file in your repository and the
patched file) using the old version of the file for reference and it works as
intended with Mono without repercussions on the behavior with Windows (since we
use your library under Windows too).
