Origin of the U+nnnn notation (original) (raw)

Next message: Dominikus Scherkl: "RE: Origin of the U+nnnn notation"

I have been unable to hunt down the historical origin of the
notation U+nnnn (where nnnn are hexadecimal digits) that we
use to refer to characters (and code points).

Presumably "U" stands for "UCS" or for "Unicode", but where does the plus
sign come from? My guess would be that it's just a separator, but
why would a separator be needed? To make the expression more easily
distinguishable (visually and automatically), perhaps.
