Technical knowledge isn't specifically bound to literacy.
A "dumb" example would be IKEA manuals that describe an assembly algorithm, I could imagine a lot of other situations where you want to convey very specific and technical information in a form that doesn't rely on a specific language (especially if languages aren't shared).
Color coding, shape standards etc. also go in that direction. The efficiency is just so big.
