Preview bug in macOS 11.5.1

A screen shot would help here. Fonts display normally for me.

2. I tried several time to print a Word 16.51 document as a PDF file to open it in Preview but Preview just showed odd pages.

I don't use Word so someone else will have to reply about this.

Preview is also working as usual for me.

The odd pages problem is for sure because of some selection in the print dialog. Preview has nothing to do with it. Check what is the option selected in the “paper handling” popup of the print dialog.

Do these problems go away when you use (the free version) of Adobe Acrobat Reader to open the same files?

This suggests to me that the pdf uses a font that is not installed in the system-hence fint substitution is taking place.

If we can figure out which font that is and the font can be downloaded and installed, that ought to do it.

In Acrobat Reader, go to File > Properties (Command D), and look at the Font tab. That will list all fonts in the document and show whether they are embedded or not.

"does not work properly" in what way?

You never said which fonts these are. Maybe some font is corrupted and Adobe uses its own version?
