What ⩵ means
A relation sign whose interpretation comes from its formula.
Its shape marks a mathematical relation, but does not specify which one. Follow any definition given with the formula; the glyph alone is not a complete rule.
Can ⩵ turn into ==?
Yes, under Unicode NFKC normalization.
Unicode's compatibility mapping expands ⩵ to two ordinary equals signs, ==. Text that undergoes NFKC may therefore store or compare the two-character sequence instead.
Don't confuse it with
1==
This is two separate equals-sign characters; ⩵ is one mathematical character. In code, use the operator spelling required by the language.
Questions people ask
1Why does ⩵ show as a box on some devices?
Because that device's fonts have no glyph for it. The character is still correct and still copies correctly — the box is a missing glyph, not a broken character.
