💡 Best Practices

Do

  • Prefer &RBarr; for readable source markup
  • Distinguish ⤐ from ⤏ (&rBarr;, single-headed) and ↠ (&Rarr;)
  • Add aria-label or surrounding text for accessibility
  • Verify your font supports Supplemental Arrows-B (U+2910)
  • Keep one entity style per project for consistency

Don’t

  • Confuse &RBarr; (U+2910) with &rBarr; (U+290F)
  • Use CSS \2910 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
  • Use HTML entities in JS (use \u2910 instead)

Key Takeaways

1

Four methods all render ⤐

&RBarr; &#x2910; &#10512;
2

For CSS, use \2910 in the content property
