Known as right angle with downwards zigzag arrow, angle with down zig-zag arrow, \rangledownzigzagarrow, and ⍼, no one knows what ⍼ is meant to represent or where it originated from. Section 22.7 Technical Symbols from the Unicode Standard
on the Miscellaneous Technical block doesn't say anything about it.
Who doesn';t love a good what-the-hell-is-this-glyph story?
