When to use it
⊆ writes U+2286 (Subset of or Equal to), a maths symbol from the Unicode Mathematical Operators block, encoded since Unicode 1.1. For more than a symbol or two, MathML, supported in all major browsers since 2023, gives proper maths spacing and layout.
The name dates from HTML 4, so it works in every browser and in old email clients.
