What means
For logos and screen artwork. On European Sharp MZ screens in the early 1980s, outlined digits and capital Latin letters were separate from their regular forms and served as ready-made graphic shapes.
The MZ line traces back to the MZ-80K, released in 1978. Unicode carried the character set forward to help old text, emulators, and terminal-style displays reproduce it.
