HarmonyOS TS侧可以通过getSystemFontList()获取系统支持的字体名称列表：是空的

1.font.getUIFontConfig能力：

import font from '@ohos.font';
@Entry
@Component
struct FontExample {
  build() {
    Column() {
      Button("getUIFontConfig")
        .width('60%')
        .height('6%')
        .margin(50)
        .onClick(()=>{
          let fontConfig = font.getUIFontConfig();
          console.log("font-dir -----------" + String(fontConfig.fontDir.length));
          for (let i = 0; i < fontConfig.fontDir.length; i ++) {
            console.log(fontConfig.fontDir[i]);
          }
          console.log("generic-------------" + String(fontConfig.generic.length));
          for (let i = 0; i < fontConfig.generic.length; i ++){
            console.log("family:" + fontConfig.generic[i].family);
            for (let j = 0; j < fontConfig.generic[i].alias.length; j ++){
              console.log(fontConfig.generic[i].alias[j].name + " " + fontConfig.generic[i].alias[j].weight);
            }
            for (let j = 0; j < fontConfig.generic[i].adjust.length; j ++){
              console.log(fontConfig.generic[i].adjust[j].weight + " " + fontConfig.generic[i].adjust[j].to);
            }
          }
          console.log("fallback------------" + String(fontConfig.fallbackGroups.length));
          for (let i = 0; i < fontConfig.fallbackGroups.length; i ++){
            console.log("fontSetName:" + fontConfig.fallbackGroups[i].fontSetName);
            for (let j = 0; j < fontConfig.fallbackGroups[i].fallback.length; j ++){
              console.log("language:" + fontConfig.fallbackGroups[i].fallback[j].language + " family:" + fontConfig.fallbackGroups[i].fallback[j].family);
            }
          }
        })
    }.width('100%')
  }
}

2.native侧获取系统字体：使用fopen、std::ifstream可以读取，路径为system/fonts。
