How to make mp4box display Russian filenames correctly?

Question

Character encoding

In the console under Windows 7 Pro SP1 64 bit Rus, the mp4box version 0.8 program displays Russian file names in squares, 2 squares per letter. There is chcp 65001 , and it includes it itself, judging by https://github.com/gpac/gpac/blob/master/applicati... , line 5931.
From the analysis of the sources, I found out what it outputs to stderr (see below). lines 5846 and beyond) I redirect stderr to a file with the help and I see that there is normal UTF-8 in the file name. The Lucida Console font is worth it. What to do? Or, as always, rebuild from source?
fprintf(stderr, "Saving to %s: ", outfile);
