💡 Best Practices

Do

  • Use <ol style="list-style-type: upper-roman"> when it’s truly a list
  • Use numeric references (&#x2163; / &#8547;) for portability
  • Verify font support for Number Forms if the glyph is critical
  • Keep numbering style consistent within a section
  • Pair with text context when needed (e.g., “Part Ⅳ”)

Don’t

  • Use Ⅳ where “IV” letters are semantically intended (they can render differently)
  • Assume all fonts include Number Forms
  • Mix uppercase and lowercase roman styles without reason
  • Use the CSS escape inside HTML content
  • Replace semantic list structure with decorative glyphs
