The original font from the dynamic highway signposts / variable-message signs (dWiSta) in Hesse, Germany!
Many non-alphanumeric characters which aren't used on the signs, are replaced with icons used on the signs, e.g.:
§ (paragraph) = Autobahn A3
% (percent) = Autobahn A5
$ (dollar) = Autobahn A67
| (vertical bar) = traffic jam
@ (at-sign) = construction
= (equal sign) = airport
# (hashtag) = stadium
etc. etc.
