Left Square Bracket Lower Corner

⎣ is the lower-left piece of an extendable square bracket. In technical typesetting, the pieces make matrix brackets tall enough for several lines. The same set can mark vertical text in terminal-emulator software outside Chinese, Japanese, and Korean layouts.

What ⎣ means

This bracket piece joins others to form a tall bracket. An upper corner and vertical extension continue its left edge; matching pieces close the right. Unlike ⌊, it is not a complete left floor symbol.

Why does ⎣ show as a box?

A missing font glyph is the likely cause. The text can still contain ⎣, but the receiving font cannot draw it. A font with technical-symbol coverage can display it.
