No. It, like all older windows programs uses ANSI by default. It can save as Unicode. Note that ANSI 0 - 127 = ASCII 0 - 127 (which also = Unicode 0 - 127).
I did actually consider being a smartarse and suggesting edlin. I remember getting Dos 3.3 home and my text editor up to that point was IBM's XEdit (really powerfull). I looked at Edlin with real dismay.
