On Windows 7, dir or tree can't show unicode characters, even starting cmd with cmd /U

So I would press Window Key + R to run something, and type in cmd /U so that the content might handle Unicode.

And then using dir or tree /F, the content in Unicode won't show as Unicode. (in Window Explorer (file manager), the Unicode will show)

Is there a way to handle it? To get Unicode characters to test your filenames, you can go to

and you will be able to get many Unicode characters there (UTF-8)
