Problem: Calibre converts non-English titles to English equivalents.

Calibre converts non-English titles to English equivalents, without regards to options.

I'm adding a large number of books in the Russian language, for example:

"Стейнбек — О мышах и людях.fb2"

Calibre copies it to the library, but renames it to:

"O myshakh i liudiakh - Dzhon Ernst Stieinbiek.fb2"

I'm using Calibre-v.5.17.0

There is an option in: Calibre-> Preferences-> "Saving books to disk"->
[] "Convert non-English characters to English equivalents"
And I have made sure that this option in NOT checked.

Is this a bug? Or is there another option somewhere I need to check?

Thanks in advance!
