U+2317 "⌗" Viewdata Square is a graphical symbol originally used in the Viewdata and teletext systems of the 1970s and 1980s, where it served as a special control character for screen formatting, often representing a filled or active square within a mosaic character set. It is classified under the “Miscellaneous Technical” block and has no standard meaning in plain text, but it sometimes appears in modern contexts as a decorative glyph or in technical documentation related to legacy terminal systems.
