HarmonyOS开发中的中文base64加密解密乱码？

let user_data_json='{"act":"GetPurchased","uid":"10074022","page":10,"tag":1,"flg":1,"title":"陈"}' 
let user_data_encode_1 = Base64.encodeToString(Base64.stringToBytes(user_data_json)); 
console.error("加"+user_data_encode_1) 
 
let decode_1 = Base64.bytesToString(Base64.decode(String(user_data_encode_1))); 
console.error("解密"+decode_1)

中文“陈”，加密后再解密无法识别，该如何转码？

参考以下代码：

let textEncoder = new util.TextEncoder("utf-8"); 
let input='{"act":"GetPurchased","uid":"10074022","page":1,"tag":1,"flg":1,"title":"陈"}'; 
let shuzu= textEncoder.encodeInto(input) 
// 解密前 
let that = new util.Base64Helper(); 
let result = that.encodeToStringSync(shuzu); 
let waitDecodeArr = that.decodeSync(result) 
 
let textDecoder = util.TextDecoder.create('utf-8') 
let decodeResult = textDecoder.decodeWithStream(waitDecodeArr)
