I'm on 10.14.6 Mojave on a brand new iMac, but still but experiencing these exact same problems with Avenir this morning. Wanted to add to the comments that it hasn't been fixed.
When exporting to PDF it sometimes knocks out the font and becomes glyphs and highlighted pink or it starts out okay when opening a document but then suddenly becomes glphs/highlighted pink. Or when initially opening document it doesn't work so close it down and open it up and it works again. Doesn't seem to matter if I have Suitcase Fusion open or not.
