What means
It lights cells 1, 2 and 4 of a 2×3 tile.
Cells 1 and 2 fill the top row; cell 4 fills the middle-right. Matching tiles form simple screen pictures.
Why are the mosaic cells separated?
The gaps preserve Teletext’s separated-mosaic mode.
British Teletext, an information service for analog TVs, began in the early 1970s and carried text and simple block graphics. ETSI specifies the separated mode in 2003.
A 2021 Unicode proposal sought distinct characters so emulators and existing software could preserve the gaps.
