How to fix the encoding in the program on visual basic 6?

Question

Character encoding

Hello!
There is a problem associated with encoding in a program written in visual basic 6, it is as follows: there are no source codes for the program, the program was written without using the Russian language, at the moment the task is to teach the program the Russian language, but when localizing strings, the program shows krakozyabry. How can you tell the program which correct encoding to use?
All lines of the program are placed in the .mdb database, which allows them to be localized without any problems.
Localization is carried out by a script that reads Russian text from a file in UTF-8 encoding and updates the entries in the program database, first converting the text encoding to CP1251.
As a result, the program displays the text like this:

The system has Russian localization for programs that do not support UTF-8.
