TL;DR

Bunch of new symbols to give the CN and Maps a little more flair (and possibly usefulness)

What ?

Add a bunch of symbols to the network, I'd suggest
the biological, chemical and radiological warning signs (or some of them https://en.wikipedia.org/wiki/Hazard_symbol)
some road signals (no entry warning exclaimation amongst others https://s-media-cache-ak0.pinimg.com/73 ... c9a4de.jpg and https://s-media-cache-ak0.pinimg.com/or ... 122b1e.gif )
Combined signals for letters/numbers and colours (so a neutral set (like now) and the colours and then Red 0-9A-Z, Green 0-9A-Z, ect..) with plain colours setting lamp colour ahead of the combined ones
Arrows (8 directions)

Why ?

New symbols are interesting and can be useful, it'd also allow for more and more circuit conditions and more and more readable conditions. For example people have made scrolling displays for text and such using almost every available symbol and deciphering this is difficult
Strictly speaking I'm sure we can get away without any of these, but Biological Warning symbols on biter nests in multiplayer would be useful.
The Nuclear symbols likewise can be useful to make Nuclear testing and the power plant
The Chemical symbols useful for marking oil and acid production
Road signals on the railway.

The warning/road symbols are almost universal outside of the game one of the sets I linked was british the other seems like it might be from an arabic country (I just googled images) and because they're so recognisable and different from in game they'll stand out on the map far more and have better usability compared to marking with an item that blends in.

The Coloured letters would provide options to have many independent signals locally collated, having say north, east, south, west and central zones of bot networks and sending all the data over the same network using the same letters for each stat but a different colour for each zone without using 20 letters for your robot stats, and limiting what else you can send.

I would add that adding new symbols is only worth the afford, if (most) new symbols are also available as possible circuit signal.
