Thank you for spending time.
I always use Notepad++ many years. In the bottom right I can see encoding.
I compare 2 files with db-backup - one from Updraftplus and one from protective plugin. And it is not my first backup, but the first experience with the version 1.12.15 and WP 4.5.3. Earlier I used version 1.11.12 and WordPress was little older...
- Upfraftplus makes file in ANSI and russian words looks like Рецепты (it because of excess operation of coding from UTF-8 to Win)
- Defense plugin makes UTF-8 file with proper words like Рецепт
