vue+ydui使用iconfont時圖標不顯示

本來我是這樣定義圖標字體的：（省略woff字體編碼）

@font-face {font-family: YDUI-ICONS;
  src: url('../../fonts/iconfont/iconfont.eot?t=1542201734648');
  src: url('../../fonts/iconfont/iconfont.eot?t=1542201734648#iefix') format('embedded-opentype'),
  url('data:application/x-font-woff;charset=utf-8;base64,...) format('woff'),
  url('../../fonts/iconfont/iconfont.ttf?t=1542201734648') format('truetype'),
  url('../../fonts/iconfont/iconfont.svg?t=1542201734648#iconfont') format('svg');
}

而後項目的圖標一直是小方框，百思不得其解：

 

而後把woff格式的字體去掉，就能夠了：

@font-face {font-family: YDUI-ICONS;
  src: url('../../fonts/iconfont/iconfont.eot?t=1542201734648');
  src: url('../../fonts/iconfont/iconfont.eot?t=1542201734648#iefix') format('embedded-opentype'),
  url('../../fonts/iconfont/iconfont.ttf?t=1542201734648') format('truetype'),
  url('../../fonts/iconfont/iconfont.svg?t=1542201734648#iconfont') format('svg');
}

效果：
