Neither A Superset Of Nor Equal To (⊉) is the Unicode character U+2289, formally named NEITHER A SUPERSET OF NOR EQUAL TO. The formal name identifies a specific logical operator rather than a generic mathematical glyph. A separately encoded comparison target is ⊈ Neither A Subset Of Nor Equal To (U+2288).
What the formal name says about Neither A Superset Of Nor Equal To
⊉ is the Unicode character named for NOR, placing it in the negated-OR operator family rather than the ordinary OR family.
The full Unicode name is the safe automatic description of this logical operator; unsupported domain-specific meanings still require reviewed evidence.

The formal-name difference between ⊉ and ⊈
⊉ (U+2289) and ⊈ (U+2288) are separate Unicode records whose formal names identify different members of the same mathematical family.
For U+2289, compare the complete formal name before substituting another family member.
Digital Representations of U+2289
U+2289 = decimal 8841 = HTML ⊉ / ⊉. A Unicode escape-style form is u2289. Its UTF-8 bytes are E2 8A 89.
Use these identifiers in markup, source code, exports, or character diagnostics when the glyph alone is not enough.
