You have to use UNICODE (WSTRING). For Example: NodeID_0.Identifier := “测试字符串\TESTSTRING”;
Important is also the definition of NodeID_0.Identifier. This must be also WSTRING.

I hope this will help you.

Thanks but the identifier is actually a defined data type of library AsOpcUac , I cannot change this STRING type to WSTRING

So you can use the IdentifierType: UAIdentifierType_Numeric.
All you have to know is the Numeric Identifier of your Variable.

I have never made it with Numeric Identifier, but you can check it.

NodeID_0. Identifier := 10240; ← Only for example! You have to use the Value from your Variables.
NodeID_0.IdentifierType := UAIdentifierType_Numeric;
