Hi Rufhs1,

Thanks for providing the details. We shall get back to you in case of any updates.

This bug seems to be specific to “PFDinDisplayPro Regular” font. We have tested many other fonts and unable to reproduce this issue. We have also found that when the font is installed, there are 2 fonts that appear in MS PowerPoint application (see screenshot). If we select the upper one (PF DinDisplay Pro), save the document and retry rendering, the font is rendered correctly.
