The following code works well on Edge 42 and Edge 44 version:
<link href="https://fonts.googleapis.com/icon?family=Material+Icons" rel="stylesheet">
<style type="text/css">
@font-face {
font-family: 'Material Icons';
font-style: normal;
font-weight: 400;
src: url(https://example.com/MaterialIcons-Regular.eot); /* For IE6-8 */
src: local('Material Icons'), local('MaterialIcons-Regular'), url(https://example.com/MaterialIcons-Regular.woff2) format('woff2'), url(https://example.com/MaterialIcons-Regular.woff) format('woff'), url(https://example.com/MaterialIcons-Regular.ttf) format('truetype');
}
.material-icons {
font-family: 'Material Icons';
font-weight: normal;
font-style: normal;
font-size: 24px; /* Preferred icon size */
display: inline-block;
line-height: 1;
text-transform: none;
letter-spacing: normal;
word-wrap: normal;
white-space: nowrap;
direction: ltr;
