Problem when I use the webdings font in firefox or inkscape

http://unix.stackexchange.com – I installed the webdings font in my computer, and it works well with LibreOffice. But when I use the webdings font in a local html page : it doesn't work, the following unicode character is diplayed instead of the wanted character . But if I export my local web page to PDF (with the wkhtmltopdf tool) I get the wanted character in the PDF. So I don't understand why it doesn't work on my local web page (I tried with firefox and chromium). If someone has an idea? I also tried in inkscape but I was unable to display my character in it. A bit of code to clarify it : /* the font in my css (HowTos)
