Adobe Acrobat adds 6s where spaces should be
This is simply a bug report.
I've come across a rather strange issue. When I choose the "Save as Adobe PDF" option in Microsoft Word, Adobe Acrobat adds these superscripted 6s where spaces should be in the text. I have tested this quite a few times, and the issue appears to be with a font I am using, "Work Sans", when I italicize the font (using Microsoft Word's italic formatting option, NOT an italic version of the font itself). This issue does not appear with other fonts I have tried. The text renders fine in Microsoft Word itself, it's only when converted to a PDF that this happens.

My fix for this has just been to not italicize the text - I can't use a different font because this is one of our brand fonts, but I wanted to report the bug either way. It's very difficult to know if this is a Microsoft Word (latest version) issue, a font issue (Work Sans OTF, downloaded from Google Fonts), or Adobe Acrobat issue (latest version). I have been having issues with Work Sans in InDesign as well, as InDesign also refuses to render italicized Work Sans properly when exporting to PDF. I have tried re-downloading the font and it has not fixed the issue.
