After updating out WordPress installation and changing some fonts we’ve got some strange images instead of arrows on next/previous posts: (U+F430) and (U+F429).
These images are utf-8 characters in the Private Use Unicode subset.
In CSS these arrows are defined as ‘\f430’ and ‘\f429’:
.single #content #nav-below .nav-next a:before { content: '\f430'; } .single #content #nav-below .nav-previous a:after { content: '\f429'; }
So, if you see these images instead of arrows, then you got another character representation than you need. The easy solution is to add a Genericons font-family tag to your css:
.single #content #nav-below .nav-next a:before { content: '\f430'; font-family: Genericons; } .single #content #nav-below .nav-previous a:after { content: '\f429'; font-family: Genericons; }
