Special characters not displayed properly in "Run" window, and .exe app

Special characters (polish special characters ę, ó, ą, ś, ł, ż, ź, ć, and █, ╗) are not displayed correctly in Run window, and in .exe application.

In IDE all characters are written correctly, but when i try to run the code I get different letters. Ex:

Ôľł instead of █,

ÔĽŚ instead of ╗,

─ś instead of Ę,

┼╗ instead of Ż.

I changed my code to be saved in UTF-8 format, I also changed file encoding to UTF-8 in CLion settings. Furthermore i worked on linux terminal previously and same code printf("█"); worked as intended there after changing source code format (textfile) to UTF-8. Did anybody encounter this issue, and if so, does anybody know how to fix it?

CLion build: 2022.3
