Underscored text in Command Prompt?

Is there any way to output underscored text in the standard Command
Prompt window? I don't want to install ANSII drivers, as I may ship my
program to people without such drivers.

An alternative would be to use overstrike characters (which may, or may
not be ¯) on the following line, but I suspect that may also involve
ANSII drivers.

I've found the character at x'EE' which is close; it's a "-" but at the
top of its box.
