Mathematical symbol Bowtie
About this character
The character ⋈ carries the official Unicode name “Mathematical symbol Bowtie” and the code point U+22C8, which is 8904 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 0x88) and 1 in UTF-16 (0x22C8). 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+22C8, which is 8904 in decimal and 021310 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+22C8. 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%88. Modern filesystems accept it, though it is still risky when moving files between systems. For passwords, some forms reject non-ASCII characters outright.
