Encoding error when reading .propeties file after editing it from notepad?

The code is written in idea. UTF8 file encoding with native-to-ascii checkbox. The file has the Russian word "ball". After assembly, we have instead

\u0448\u0430\u0440\u0430 

Everything works, until the replacement of these characters manually from notepad. Somewhere I found information that needs to be used.

 properties.getProperty("db.host").getBytes("CP866") 

But it did not help
