reactjs - DraftJS Modifier.insertText(): Unicode の挿入

Question

私は絵文字のリストを持っています。それぞれに独自のユニコードがあります。Modifier.insertText() を使用して、それらをテキストに挿入したいと思います。

_addEmoji(text) {
    const { editorState } = this.state;
    const selection = editorState.getSelection();
    const contentState = editorState.getCurrentContent();
    const txt = '&#x' + text + ';';
    let nextEditorState = EditorState.createEmpty();
    if (selection.isCollapsed()) {
      const nextContentState = Modifier.insertText(contentState, selection, txt);
      nextEditorState = EditorState.push(
        editorState,
        nextContentState,
        'insert-characters'
      );
    } else {
      const nextContentState = Modifier.replaceText(contentState, selection, text);
      nextEditorState = EditorState.push(
        editorState,
        nextContentState,
        'insert-characters'
      );
    }
    this.onChange(nextEditorState);
  }
