I have encountered a unique issue where only certain Font Awesome icons are missing, and this problem is limited to Internet Explorer and Safari browsers.
It seems that the icons with a "content" value of "\f20d" and higher are the ones affected...
For example, when I use the class for the "fa-meanpath" icon (which has a content value of \f20c), the icon displays correctly.
However, if I switch to the "fa-buysellads" icon (which has a content value of \f20d) or any icon with a higher value, they do not appear at all. The space remains blank with no sign of the icon.
Icons with values lower than \f20c seem to work without any issues...
I have confirmed the list of icons on
and those same icons display properly on that website in IE and Safari. However, on my site, these specific icons fail to render in those browsers (including iPhone).
What steps can I take to troubleshoot this unusual problem?
