💡 Best Practices

Do

  • Use &#x2901; or &#10497; for HTML markup
  • Add aria-label or surrounding text for accessibility
  • Distinguish ⤁ from ↠ (plain two headed) and ⤏ (triple dash)
  • Verify your font supports Supplemental Arrows-B (U+2901)
  • Keep one entity style per project for consistency

Don’t

  • Confuse ⤁ with ↠ (plain two headed arrow) or ⤏ (triple dash)
  • Assume a named HTML entity exists—there is none for U+2901
  • Use CSS \2901 inside HTML text nodes
  • Rely on the arrow alone without context for screen readers
  • Mix entity styles randomly in one file
  • Assume all fonts render supplemental arrow glyphs identically

Key Takeaways

1

Two HTML references plus CSS all render ⤁
