Precedes Under Relation (⊰) is the Unicode character U+22B0, formally named PRECEDES UNDER RELATION. PRECEDES establishes the direction of the relation; UNDER RELATION further identifies the named variant. The corresponding SUCCEEDS form is a different Unicode character. A separately encoded comparison target is ⊱ Succeeds Under Relation (U+22B1).
The precedes relation encoded by ⊰
⊰ is named for a precedes relation. Unicode therefore treats it as a mathematical relation character, not merely as a decorative curved less-than shape.
UNDER RELATION narrows the PRECEDES family to this named variant. The corresponding SUCCEEDS UNDER RELATION character reverses the reading and has another code point.

Why U+22B0 and U+22B1 remain separate characters
⊰ (U+22B0) says PRECEDES UNDER RELATION. Its named counterpart ⊱ (U+22B1) says SUCCEEDS UNDER RELATION. The pair therefore differs by relation direction, not by font styling.
For U+22B0, PRECEDES is the directional word that must survive any character replacement.
How ⊰ Is Encoded
U+22B0 = decimal 8880 = HTML ⊰ / ⊰. A Unicode escape-style form is u22B0. Its UTF-8 bytes are E2 8A B0.
Use these identifiers in markup, source code, exports, or character diagnostics when the glyph alone is not enough.
