With the current serif typeface it's easy to mix up several characters between each others.

for example the number "6" looks like too much the number "8", same issue for some letter like l or i, Q or O.

it would be better to use a clearer serif typeface (something like Times new roman) something less confusing than the current stylized one.

arma 2 has a clearer serif typeface than arma 3.
