witraze As of January 2018, you have been worrying about 7% of browser users.
If IE9 and below (ugh) you could load a different stylesheet altogether with conditional code
<!--[if IE]>
<link rel="stylesheet" type="text/css" href="all-ie-only.css" />
<![endif]-->
IE 10, 11 requires mediaqueries instead and assign a known font, eg @import url(http://fonts.googleapis.com/css?family=Oswald:300&subset=latin,latin-ext);
<-- note force-import of latin-ext
@media all and (-ms-high-contrast: none), (-ms-high-contrast: active) {
/* IE10+ CSS styles go here */
}
Edge 12 yet *another* mediaquery
@supports (-ms-accelerator:true) {
/* IE Edge 12+ CSS styles go here */
}
