🔢 Mathematics

Specialized notation involving reversed prime marks in formulas.

📝 Typography

Professional typesetting and typographic reference systems.

💡 Best Practices

Do

  • Use &#x2036; or &#8246; for inline reverse double prime marks
  • Set <meta charset="utf-8"> for reliable rendering
  • Use ‶ for reversed double prime—not standard double prime ″
  • Test rendering in your target fonts for General Punctuation
  • Pick one numeric style per project for consistency

Don’t

  • Confuse ‶ with double prime ″ or reversed single prime ‵
  • Use padded Unicode notation like U+02036—the correct value is U+2036
  • Use CSS escape \2036 in HTML text nodes
  • Substitute straight quotes (") when ‶ is required typographically
  • Assume every font renders prime symbols identically

Key Takeaways
