Thanks for contacting Syncfusion support.
At present, we don’t have custom font style support in Gantt PDF export. Hence, we have logged a feature report as “Custom styles support for Pdf export”. This feature will be implemented and included in our upcoming volume 4 main release.
Please let us know, if you require any other assistance.
