Mathematical symbol Triple Tilde
About this character
The character ≋ carries the official Unicode name “Mathematical symbol Triple Tilde” and the code point U+224B, which is 8779 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 0x8B) and 1 in UTF-16 (0x224B). 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+224B, which is 8779 in decimal and 021113 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+224B. 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%8B. Modern filesystems accept it, though it is still risky when moving files between systems. For passwords, some forms reject non-ASCII characters outright.
