Icon on IE

Nice plugin! I tried 5 different plugins that support Toggle shortcodes on a number of different browsers, and this one works the best.

The only issue I found was that the icon does not show in any version of Internet Explorer (7, 8, 9 or 10). The “active” styling works, and the mouse pointer becomes a hand, so this is not a deal breaker. But the icon does look good, so it would be nice if it worked in at least IE 9 and 10.

I tried tweaking the @fontface settings you have in the icon css. But I know nothing about fonts, and nothing I tried worked (I was just guessing). If there is a way to solve this icon issue, it would be nice to address it.

Any way you could help?
