Will ⋅ survive being pasted?
- Normalisation. Yes. ⋅ is unchanged by NFKC, so it survives normalising systems intact.
- Legacy encodings. ⋅ is Unicode-only — it has no Latin-1 equivalent, so a system stuck on an 8-bit encoding cannot represent it.
- Size. 3 bytes in UTF-8. Character-limited fields — SMS, bios, some form validators — usually count bytes, not characters.
Unicode cross-references
The standard points readers of ⋅ at these characters — usually because they look alike, or because one is the correct choice where the other is often used by mistake.
Other operator characters
Unicode names 24 characters ending in “operator”. They differ by direction, weight or decoration rather than by meaning.
Nearby in Mathematical Operators
The operators mathematics and programming share — set theory, logic, calculus, comparison. Almost every character here has a LaTeX command, which is usually the fastest way to name the one you mean.

About Unicode’s Math symbol category
Unicode classifies this as a mathematical symbol, which means software that lays out formulas treats it as an operator or relation and gives it spacing accordingly, rather than setting it tight against its neighbours like a letter.
