Reply To: Product tabs icon

If I se the below code for the ‘review’ tab in accordeon widget I get only a small square as an icon instead of a star icon.

/* Iconen reviews in tabs op single page */
.single-product .tab-title-reviews {
position: relative;
padding-left: 20px;
}
/* Iconen reviews in tabs op single page */
.single-product .tab-title-reviews .wd-accordion-title-text:before {
content: “\e915”;
font-family: “woodmart-font”;
font-weight: 400;

position: absolute;
left: 0;
}
