Hahaha, you are totally right, good catch! Though a quick search
online shows both variations the backslash is the correct
international version. To be fair it looks like we just got this from
BeOS:

I tried this code and it looks pretty good but there is a slight
variation between the two symbols on each mini monitor. I guess this
is the anti-aliasing at work again. Of course if you compare it to the
above BeOS screenshot it definitely looks a lot better.
Regarding the topic of this thread, shouldn't there be a way to undo
the antialiased line with the right combination of colors and drawing
mode? In other words a sort of inverse antialias? If not maybe we
could add something like that, assuming it is possible.
