Our webdesigner has created a CSS with the following font-face:
@font-face {
font-family: \'oxygenregular\';
src: url(\'oxygen-regular-webfont.eot\')
Make sure that it is not a pathing issue, i.e. your CSS file is relative to where the fonts are. In your case, you need your CSS file in the same folder as your font files.
I've faced with the same issue.
In case if header of the .eot file contains Cache-Control: no-cache value, IE9 doesn't load font properly. Dev Tools showed Result - 200, but column Received showed 400B, in the same time Content-Length was 70Kb. I've used following value Cache-Control: max-age=0, to fix issue.
