If you're on Windows (where Microsoft famously chose they would not get involved with flags and show country codes instead), execute this in dev tools or save it as a javascript bookmarklet to make the emoji flags show up: javascript:(function(){if(!document.getElementById('twemoji-styles')){const s=document.createElement('style');s.id='twemoji-styles';s.textContent='img.emoji{height:1em!important;width:1em!important;margin:0 .05em 0 .1em!important;vertical-align:-0.1em!important;display:inline!important;}';document.head.appendChild(s)}const r=()=>{const o={folder:'svg',ext:'.svg'};twemoji.parse(document.body,o);if(!window.__twemojiObserver){let t;const ob=new MutationObserver(()=>{clearTimeout(t);t=setTimeout(()=>{ob.disconnect();twemoji.parse(document.body,o);ob.observe(document.body,{childList:true,subtree:true});},300);});ob.observe(document.body,{childList:true,subtree:true});window.__twemojiObserver=ob;}};if(window.twemoji){r();}else{const sc=document.createElement('script');sc.src='https://cdn.jsdelivr.net/npm/@twemoji/api@latest/dist/twemoji.min.js';sc.crossOrigin='anonymous';sc.onload=r;document.head.appendChild(sc);}})();
