Output parameters of the RawUtf8 type are incorrectly displayed

my code define as follows：：

  IUserManage = interface(IInvokable)
  ['{970EB610-FC4B-4A89-9A39-2767A5100F97}']
    function chgMyPwd(oldPwd,newPwd:RawUtf8;hashed:Boolean;out errMsg:RawUtf8):boolean;
  end; 

  If errmsg returns a Chinese string, the client displays it incorrectly, but if errmsg is of type string, the return is correct.

  I don't know why.

Re: Output parameters of the RawUtf8 type are incorrectly displayed

If errmsg returns a Chinese string, the client displays it incorrectly, but if errmsg is of type string, the return is correct. I don't know why.

With this minimal information, I can only guess:

var s: String := Utf8ToString(errMsg);

With best regards

I tried it, but using Utf8ToString(errMsg) didn't solve the problem.
What happens to the RawUtf8 parameter? English can be returned normally.

你可以试试这个: utf8tocp936(stringtoutf8(errMsg))

不行，我看了返回值的16进制数字，原始字符串：out测试，  返回的16进制表示：6F7574 C3A6C2B5C28B C3A8C2AFC295，正确的UTF8编码：6F7574 E6B58B E8AF95
