How to write a Russian string in UTF-8 and/or cp1251 to a file?

Question

Java

The Russian string that needs to be written to the file is stored directly in the code:
String someValue = "Поехали!";
I tried to write to the file like this:

BufferedWriter bw = new BufferedWriter(
    new OutputStreamWriter(new FileOutputStream(targetFilePath))
);        
bw.write(someValue + "\n");
bw.close();

The result in notepad (notepad.exe) is:

???????!

I tried to use different encodings (utf-8, utf-16, cp1251) in the OutputStreamWriter constructor, but I did not see the Russian text. I tried to watch in different encodings through Sublime and EditPad Lite, I don’t see Russian either.
How to save the Russian text specified in the code to a file?
