Subject: [PATCH] Polish vowels in PDF
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Using moodle in Polish language so, writing item contents in Polish, causes the pdf of a single response with special chars like: ąčęėįšųūž to be reported as ????????.
Changing the PDF font to freesans, seems to fix the problem.
