Mathematical symbol Subset of
About this character
The character ⊂ carries the official Unicode name “Mathematical symbol Subset of” and the code point U+2282, which is 8834 in decimal. It belongs to the Mathematical Operators block (U+2200–U+22FF), which gathers the operators, quantifiers and relations of algebra, logic and set theory.
In memory, ⊂ takes 3 bytes in UTF-8 (0xE2 0x8A 0x82) and 1 in UTF-16 (0x2282). That difference is why badly configured forms or databases garble this character: they assume one byte per character.

Frequently asked questions
What is the Unicode code for ⊂?
Its code point is U+2282, which is 8834 in decimal and 021202 in octal. In HTML you can write it as ⊂ or ⊂.
Why does ⊂ show up as a box or a question mark?
An empty box means the font has no glyph for U+2282. The character is still in the text: switching to a font that covers the block (Noto, DejaVu or Segoe UI Symbol) makes it appear.
Can I use ⊂ in a filename, a URL or a password?
In a URL it must be encoded as %E2%8A%82. Modern filesystems accept it, though it is still risky when moving files between systems. For passwords, some forms reject non-ASCII characters outright.
