Mathematical symbol Not Equivalent to
About this character
The character ≭ carries the official Unicode name “Mathematical symbol Not Equivalent to” and the code point U+226D, which is 8813 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 0x89 0xAD) and 1 in UTF-16 (0x226D). 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+226D, which is 8813 in decimal and 021155 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+226D. 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%89%AD. Modern filesystems accept it, though it is still risky when moving files between systems. For passwords, some forms reject non-ASCII characters outright.
