Hello, yes i did some customization to adapt color (style.css) & remove some parts  of the page (template-home.php). I don’t find a link from what i modified to the font issue. But, now, wordpress 4.3.1 was just automatically been installed and it has fixed the isssue !! the correct font/symbol is displayed again !!! (just for information can you tell me what happened ? a link to the font library was broken and rebuilt during update process ? thanks for sharing.
