HarmonyOS TextInput组件添加了inputFilter属性关联正则表达式出现异常

复现demo：

@Entry
@Component
struct toastExample {
  build() {
    Column() {
      TextInput({placeholder:'仅支持中英文、数字'})
        // .type(InputType.USER_NAME)
        .cancelButton({ style: CancelButtonStyle.INPUT, icon: { size:15 }})
        .fontSize(15)
        .maxLength(20)
        .inputFilter('^[\u4e00-\u9fa5A-Za-z0-9]{1,20}$')
        .backgroundColor(Color.White)
        .enterKeyType(EnterKeyType.Done)
        .height(50)
        .margin({ left: 0, right: 10 })
        .onChange((value: string) => {
          console.info(value);
        })
        .onFocus(() => {
          console.info('获取焦点');
        })
    }.height('100%').width('100%').justifyContent(FlexAlign.Center)
  }
}
