What ⨗ means
It is an integral sign marked with a left-pointing hooked arrow. The glyph names its visible parts, but not what is integrated or what the arrow contributes. The MathML 3 operator dictionary marks it as a prefix large operator, a layout instruction rather than a mathematical definition. Use the author’s notation key to learn what it means in a particular formula.
What did MathML record before Unicode?
MathML listed a private-use version in 1998. Its table assigned the glyph the code E39A, a private-use code reserved for document- or font-specific characters. That is an earlier markup encoding; the current character identity is the assigned Unicode character ⨗.

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.
