Will | survive being pasted?

  • Normalisation. No. Anything that applies NFKC — search indexes, usernames, domain names, programming identifiers — rewrites | as |. Safe for display, not for storage.
  • 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.

Other line characters

Unicode names 6 characters ending in “line”. They differ by direction, weight or decoration rather than by meaning.

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.
