What ⫠ means
The 2000 proposal gives it no standalone gloss.
That Unicode/ISO math-symbol proposal groups ⫠ with tack and turnstile signs and cross-references it to , the up tack. The reference alone does not establish that the two marks are interchangeable; use the definitions of the notation around ⫠.
Why can ⫠ look different in different fonts?
The visible shape depends on the font.
A font draws the glyph for this text character, so its outline and proportions can vary while the underlying character remains ⫠.
Questions people ask
1Why does ⫠ show as a box on some devices?
Because that device's fonts have no glyph for it. The character is still correct and still copies correctly — the box is a missing glyph, not a broken character.
