💡 Best Practices

Do

  • Prefer &nlArr; in HTML for readability
  • Pair ⇍ with text (“Previous”, “Back”) or aria-label for accessibility
  • Use fonts that support the Arrows block (U+21CD)
  • Set <meta charset="utf-8">
  • Keep one encoding style per project for consistency
  • Distinguish ⇍ from ⇐ when stroke vs plain double arrow matters

Don’t

  • Confuse &nlArr; (U+21CD) with &lArr; (U+21D0, plain left double arrow)
  • Confuse &nlArr; with &larr; (U+2190, simple left arrow)
  • Use CSS \21CD inside HTML text nodes
  • Assume ⇍ always means logical negation without context
  • Mix named and numeric entities inconsistently in the same component
