Mathematical symbol Not Square Original of or Equal to
About this character
The character ⋣ carries the official Unicode name “Mathematical symbol Not Square Original of or Equal to” and the code point U+22E3, which is 8931 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 0x8B 0xA3) and 1 in UTF-16 (0x22E3). 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+22E3, which is 8931 in decimal and 021343 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+22E3. 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%8B%A3. Modern filesystems accept it, though it is still risky when moving files between systems. For passwords, some forms reject non-ASCII characters outright.
