@font-face not working with specific version of Internet Explorer 11
This could be related to an issue with the Security Settings as described in this bug report.
In Internet Options go to:
- The Security Tab
- Security level for this zone
- Custom level

If it's Disabled then you need to Enable it.
Font-Face not working in IE or Edge
If anyone stumbles across this post, I ended up just using a more web-friendly font.
Make sure your @font-face rules are NOT contained in media queries. @font-face rules contained in media queries do not work in IE, Edge, but work in every other modern browser I tested on.
@font-face not displaying correctly in IE
Multiple font formats
To support a wide range of browsers, use a .ttf,
.woff
and .eot
version of the font.
@font-face {
font-family: 'shardee';
src: url('fonts/Shardee.eot');
src: url('fonts/Shardee.eot?#iefix')
format('embedded-opentype'),
url('fonts/Shardee.woff') format('woff'),
url('fonts/Shardee.ttf') format('truetype');
}
You can use a Font conversion website like Font Squirrel, to convert the .ttf
font into .woff
and .eot
.
DRM false positive
As @Jukka pointed out, there's a legal issue with the TTF file that's preventing it from being usable in Windows. In the IE developer console, the following error message is displayed :
CSS3114: @font-face failed OpenType embedding permission check.
Permission must be Installable.
Shardee appears to be an abandoned font with an unknown license type. Although it may be legal to use this font, Windows seems to require that every TTF file has DRM info that explicitly says it's legal to embed it in web pages. The error in IE is most likely a false positive.
To test this, I took a TTF font that's known to be legally licensed for use on websites. The TTF version didn't work in IE because of the DRM error. This example is definitely a false positive. This is one of the reasons why it's necessary to use multiple font formats, and why a single format like TTF will not work on all browsers.
Although Windows doesn't allow IE to use the TTF file, IE can still use the WOFF or EOT version. When I tested the above @font-face
rule on a local webserver, using all three font formats, the Shardee font rendered correctly in all versions of IE (though with an error message in the IE developer console).
Steps to try:
- Convert the
.ttf
file to.woff
and.eot
- Upload the
.woff
and.eot
files to the same directory as the existing.ttf
file. - Replace the
@font-face
rule with the one above. I fixed a couple typos in the initial version of it.
If you still have a problem, there may be an issue with the web server settings. Related question: IE9 blocks download of cross-origin web font
