Not if you do it using chcp on the command line, or (presumably) SetConsoleCP
in the Windows API.

I don't have to prepend a zero anyway.  It just produces a different character
if I do.  Traditionally at least, with a 0 it types a character from the ANSI
set, and without a 0 it types a character from the OEM set.

But as I test it (Win7), it depends on what font the command prompt is set to.

The sequence of strange characters is Alt+0163, Alt+163, Alt+0156, Alt+156 in
each case.
