No.  At the very least, symbol fonts for math usage have arrows in them.
 Also, Unicode has code positions designated as arrows.

So the pieces are floating around for us to do this "right".

And if we want a more hackish solution, then let's forget about Latin-1
*and* about Mac Roman.  Go back to the old font used on IBM PC's, which
indeed has arrows in it.  I think character 27 was the left arrow.  :) 
I don't think it has too many accented vowels, but then again it also
has plenty of line-drawing characters.  That way when you log into a BBS
from Squeak the ASCII art will look excellent.
