UTF-16 file output in cmd.exe

Question

chcp 10000
echo hell☺ w☻rld♥! >> "UTF-16 file☺☻♥♦♣♠"

OK, it creates correct file, but in the content there are question marks instead of unicode characters. How to fix it?

I'm not sure what you are trying to do here, but that's not a Unicode code page. See http://msdn.microsoft.com/en-us/library/windows/desktop/dd317756%28v=vs.85%29.aspx.

10000   macintosh   MAC Roman; Western European (Mac)
...
1200    utf-16      Unicode UTF-16, little endian byte order (BMP of ISO 10646); available only to managed applications
1201    unicodeFFFE Unicode UTF-16, big endian byte order; available only to managed applications
...
12000   utf-32      Unicode UTF-32, little endian byte order; available only to managed applications
12001   utf-32BE    Unicode UTF-32, big endian byte order; available only to managed applications
...
65000   utf-7       Unicode (UTF-7)
65001   utf-8       Unicode (UTF-8)

I'm not sure why, but the Command Prompt seems to interpret them as control characters when pasted, specifically SOH (Start of Heading, 01), STX (Start of Text, 02) and ETX (End of Text, 03).

On the plus side, PowerShell seems to handle this properly. Notepad++ opened the resultant text file as "UCS-2 Little Endian" automatically, and it displays the correct characters.

Ok, I've figured out why UTF-8 wasn't working for me. The font should be set to Lucida Console, since the default Raster Fonts don't have Unicode support.
