TIMTOWTDI, as usual. From the "U+0370 – U+03FF Greek and Coptic" code block: 

# decimal 916 is hex 394
perl -le 'binmode STDOUT,":utf8"; print "\x{394}"'

That's for UNIX/Linux systems, use with e.g. gnome-terminal. The binmode call is in there to defeat perl's "Wide character in print" warning.

Porting to other random operating systems is left as an excercise to the reader.
Of course, you must have the appropriate fonts installed on your system to display unicode characters at the terminal.
Check out http://decodeunicode.org for other symbols.
