Segment display/Seven-segment display/O

The glyphs of the European (i.e. made up of Latin, Greek, Cyrillic script) uppercase O and lowercase letter o share similarities among the Latin scripts, at least in one of their cases. It hence makes sense to treat them together in segmental representation, even though they may represent different purposes and sounds
