It's worth noting that in 1963 ASCII, hex 5E was the up-arrow (now the
circumflex) and hex 5F was the left-arrow (now underline).

It's also worth nothing that in the original CDC 6-bit display code,
there were symbols, not only for left-to-right arrow, but not equals,
logical OR and AND, up- and down-arrow, equivalence, logical NOT,
less-than-or-equal, and greater-than-or equal--pretty much the original
Algool-60 special characters.
