HarmonyOS 什么时候支持iconfont？

//entryAbility.ts  
//font需要依赖UIContext所以需要在windowStage加载页面完成之后去注册  
 windowStage.loadContent('pages/Page', (err) => {  
      font.registerFont({  
        familyName: 'iconfont',  
        familySrc: $rawfile('AlimamaDaoLiTi.ttf')  
      })  
      if (err.code) {  
        hilog.error(0x0000, 'testTag', 'Failed to load the content. Cause: %{public}s', JSON.stringify(err) ?? '');  
        return;  
      }  
      hilog.info(0x0000, 'testTag', 'Succeeded in loading the content.');  
    });
//Page.ets  
@Entry  
@Component  
struct Index {  
  @State message: string = 'Hello World';  
  build() {  
    Row() {  
      Column() {  
        Text("\ue6fb")  
          .fontSize(50)  
          .fontWeight(FontWeight.Bold)  
          .fontFamily("iconfont")  
      }  
      .width('100%')  
    }  
    .height('100%')  
  }  
}
