You need to use FindWindowW and make sure the text is encoded as UTF16

Then clearly you are not passing correctly encoded text, or there is no window with that name.

Try inserting{$codepage utf8}on top of your unit without any casts (i.e.FindWindowW(nil, '你好，世界');). Read string literals in this topic.
