No text, but a visual code

The whole thing could be even more complicated, there is an obvious Arab 9, the con - abbr. and there could be Roman numerals as well, EVA-i as  i, EVA-l as x, Roman I and X. Not that I think so, for example I think the 8 is an ordinary Latin abbr., but there are possibilities, esspeially if you take into account that these abbr. could have multiple meanings, for example 9 as Arab 9 and the different meanings as a Latin abbr.  But your 'I see 4 and 8' does not hold

Edit: I have forgottrn EVA-o, which could be an Arab Null
