I got this problem recently.

As you can see the font of my installer replaced with square bordered A. I have tried to clean the font cache and everything but it doesn't help. Anyone have solution for this other than reinstall the OS? Thank you

Have you deleted or disabled any system fonts? Make sure the fonts in /System/Library/Fonts and /Library/Fonts match the ones in your backup.

Maybe your Font cache go messed up. Have you cleared the Font cache and rebooted to see if that helps?
