Hi Alex,


You can use the Base 64 Encode and Decode technique, where you have to encode your Non-English character before you are going to save/update. For fetching this record back you have to decode back this encoded data. This is directly supported by our SDK.

For getting more detail please have a look at 10th point in this link

In case if you have any other queries please do feel free to reach out to us. We will be happy to help you.

Hello, thanks for your solution. I have tried this Base 64 Encode and Decode technique ,but it still wont work for somehow:
my input:
    var userName  = "你好啊"
    var encodedString = Base64.encode(userName);
    console.log("Encoded String is : " + encodedString)
    var decodedString = Base64.decode(encodedString)
    console.log("Decoded String is : " + decodedString)
i got:
 Encoded String is : YH1K
 Decoded String is : `}J
