Text being converted to symbols when exporting to PDF
Hi there,
I am having an issue with XD where some of my text is being converted to symbols upon exporting the artboard to PDF, however other parts of the text are fine.
Here is what it looks like in XD:

And here is what it looks like after exporting to PDF in Adobe Acrobat Pro DC:

I thought it was an issue with Acrobat, but when opening the PDF in a browser like Chrome, the same effect happens.
The problem seems to be with the font family. I am using Avenir Black for the text that gets corrupted, and Avenir Book for the text that is fine. These fonts are installed onto my computer, and work with other Adobe programs such as InDesign and Photoshop.
Does anyone have any suggestions or am I forced to change to a different font?
Thanks.
For reference:
OS: Windows 10 x64
XD Ver: 43.0.12.14
Font: Avenir Black & Heavy
