Using this KP_Space symbol as a stand-in for the symbol 2 doesn't make sense. It looks like a mistake, or as if someone had a broken keyboard and used KP_Space as a substitute for 2.
Also, no keyboard layout in the last fifteen years has contained the KP_Space symbol, so I don't see how anyone could type it.
