Forum issue rendering of the number nine and colon

mc

This is a weird one but the forum renders the number nine (even writing this post) as an em-dash (or maybe horizontal bar) and does not render a colon. This happens for me on Firefox and Vivaldi with new profiles and no add-ons; Windows 10; Keyboard en-us. Is this happening for anyone?

An example:: is the post
https://forums.zotero.org/discussion/100282/worse-than-useless-journal-abbreviaions

where, "10.15388/CrimLithuan.2021.9.5" (that is, ...1.nine.5) is rendered as "10.15388/CrimLithuan.2021.—.5" (that is ...1.em-dash.5). If I put this text in html code tags renders correctly (that is, 10.15388/CrimLithuan.2021.9.5 but not in typing this post).

If I copy and paste the text from the forum into another site's browser text box, the number nine and colon show up correctly.

As I said, weird. Any suggestions?

The first result I get in Google for the search number 9 displayed as em-dash is:

This is probably not related with the Zotero forum.

Thanks @mjthoraval not the exact solution, but it has pointed me in the right direction. It does seem to be a problem with the fonts on my desktop. I have never had an issue with fonts before so did not even think of that. So now to reinstall them...
