Morphology

unmappable = mappable (transparent) = un + map + able

The adjective is the negative of 'mappable' (map + -able); the technical sense of 'representable in a system' follows the same morphological logic.

Etymology

Unmappable is made of un- ('not'), map ('to match or place one thing into another') and -able ('able to'). In computers, 'map' often means 'put data into a different form', so unmappable describes data or characters that cannot be matched or converted into the system.
