Hello again, everyone!

In one application that was developed not by me i have reload data and got "???? ?????" instead of data.

How to repair it?

Wild guess, but is your database using some non English character set ?

Russian symbols

Then I'd suggest checking the character sets on your Qlik Machine.  I know nothing about Russian character sets, but if they use them at your place then I expect someone there does.
