Neither A Subset Of Nor Equal To (⊈) is the Unicode character U+2288, formally named NEITHER A SUBSET 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 Superset Of Nor Equal To (U+2289).
What the formal name says about Neither A Subset 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.

Encoding ⊈ in HTML and Source Text
U+2288 = decimal 8840 = HTML ⊈ / ⊈. A Unicode escape-style form is u2288. Its UTF-8 bytes are E2 8A 88.
Use these identifiers in markup, source code, exports, or character diagnostics when the glyph alone is not enough.
Why U+2288 and U+2289 remain separate characters
⊈ (U+2288) and ⊉ (U+2289) are separate Unicode records whose formal names identify different members of the same mathematical family.
For U+2288, compare the complete formal name before substituting another family member.
