the 'dir' command in Win cmd works in Unicode regardless the code page;it's one of those Windows quirks.Go ahead change the code page to eg Cyrillic and try it out,you'll get the same result
In cp950: dir/b It shows the files with Unicode char correctly. However, dir/b > list.txt the content inside list turns into "????"
Is list.txt saved as ANSI (default)?.
Save list.txt as Unicode and try again
In cp65001: dir/b It shows the files with monster char. However, dir/b > list.txt gives the correct list.
I guess cp65001 sets the file i/o to Unicode,that is why you see list.txt with correct list
what is a monster char?
maybe a font issue? what font are you using, Lucida Console?
