The specific characters for languages other then English are not displayed in the PDF reports by default. It is possible to turn them on by specifying font that will be used in the PDF report. The font should support characters to be display and should be defined in the opinio.properties file, example:

        objectplanet.survey.report.pdf.font=c:\\windows\\fonts\\ARIALUNI.TTF
                                

The defined font should exist on the server at the given path.
