I don't like the solution that cannot be easy copy/paste-d to text files.So few more ways:

1) mshta (can be directly used in batch file or from command line):

mshta vbscript:execute("CreateObject(""Scripting.FileSystemObject"").GetStandardStream(1).Write( Chr(00) ):Close")>testfile

2) certutil (requires a temp file)

echo 00>null.hex
certutil -decodehex null.hex null.bin

3) makecab just check the subroutine here - http://ss64.com/nt/syntax-genchr.html
