non-Latin characters in Windows console

[v0lt]

Can not read the names of the DirectShow audio device in Windows 7 with the Russian locale.

How to reproduce:

Do you think it is outputting in UTF-8? hmmm I will probably just add some ability to specify device by "number" to overcome this, it is a worse problem than I thought.

I chose the font "Lucida Console" for the default console window. Sometimes this helps, but not in the case of ffmpeg.

I think you need to specify output to the console in the UTF-16 encoding.

_setmode(_fileno(stdout), _O_U16TEXT);

Really! ​https://stackoverflow.com/questions/14109024/how-to-make-unicode-charset-in-cmd-exe-by-default

This is enough to solve this!
You just call cmd /K chcp 65001
But there should be a way to change it in C!

After googling here you are an implementation in curl:

And here one uses SetConsoleOutputCP(65001) function.

All of it discussed here ​https://dev.to/mattn/please-stop-hack-chcp-65001-27db

Thank you.
The batch file below works correctly for me.

chcp 65001
ffmpeg -list_devices true -f dshow -i dummy
pause
