如何从Angular视图中的字符串转换unicode？

export class AppComponent {
  unicodeString: string;
  
  convertToUnicode(inputString: string): string {
    let unicodeString = '';
    for (let i = 0; i < inputString.length; i++) {
      unicodeString += '\\u' + inputString.charCodeAt(i).toString(16).toUpperCase();
    }
    return unicodeString;
  }
}

<input [(ngModel)]="inputString" placeholder="输入字符串">
<button (click)="unicodeString = convertToUnicode(inputString)">转换为Unicode</button>
<p>转换后的Unicode字符串: {{ unicodeString }}</p>
