Parallel To Symbol ∥
∥ is parallel to. Write it in HTML as ∥ or paste the character directly. It was added in Unicode 1.1, and Unicode files it under Math symbol.

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 parallel characters
Unicode names 6 characters ending in “parallel”. 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.
