How to search the contents of a file in Chinese encoding in Total Commander?

Question

Total Commander

Please tell me, I'm searching through the contents of the files.
Files of different formats contain text with Chinese characters, as well as Chinese encoding files.
In general, it finds content (eng words) in these files, but it does not find Chinese characters.
At the same time, I see them in the notepad in a normal form (example: 色石)
Actually, how to force the total to search for Chinese characters / letters?
