The character set is very important because depending on what character
set that your system is running determines the character. Like Jeff
Weisberg pointed out the resulting character depends on what character
set you are using. The DOS system usually defaulted to CP437 which was
an 8 bit character set. The various DOS systems called CP437 ASCII
which was really not true, since the original ASCII is a 7 bit
character set.
What I think you are asking for is how to get terminal support for CP437
so that you can display 8bit CP437 characters. In your efforts to
create ASCII art you might end up with something totally different than
what you envision. For example let's say that your recipient is using a
different character set than what you created your art in, then they
will not see the same thing that you originally envisioned. The thing
about DOS was that it was set up to be country specific where it was
sold. The DOS sold in Germany had a German character set whereas the US
version had a CP437 Character set. With Linux where it is downloaded
from the Internet, each user sets up their console for themselves. The
default for US users is en_US using the 7 bit character set.
I realize that there are

Are you sure?

If you changed the codepage in the old msdos the results would reflect
the codepage character set.
