''duplicate of https://support.mozilla.org/en-US/questions/1089212 - locking'' Hi, using Wingdings in one web application. This font seems to be Microsoft font which I came to know from Google. When the webpage is accessed using Firefox on Windows (7,8,2012), symbols show up perfectly fine. But when the same page is accessed using Firefox on Linux, the symbols do not show up. Every link on the web says Firefox does not support Wingdings Symbols and Unicode is to be used. Not quite sure if that is the case how the website is working perfectly fine on Windows. Would like to know if there is any way we can make Firefox display symbols on Linux as well.
