Use Aspose.PDF for .NET in Linux docker container - System.NotSupportedException Exception occurs

We have Aspose.PDF being used on our website hosted in a Linux docker container. When attempting to fill a combo box I am getting the folowing error “System.NotSupportedException: ‘Format of font “Symbol” is not supported for new composite fonts’”. The rest of the pdf is using the same font as the combo box. Wondering if you can giving me specifics on what may be the issue here?


Would you please try to copy all Windows fonts to your docker container or install Microsoft Essential Fonts package in OS. In case you still face any issue, please share your sample PDF document along with sample code snippet and environment details. We will test the scenario in our environment and address it accordingly.
