emoji bug

Unicode bug???

// emoji bug
`🍅🍅🍅🍅🍅💩💩💩💩💩`.slice(4, 9)
// "🍅🍅�"
`🍅🍅🍅🍅🍅⭐️⭐️⭐️⭐️⭐️`.slice(4, 9)
// "🍅🍅�"

`★★★★★☆☆☆☆☆`.slice(4, 9)
// "★☆☆☆☆"

solution OK


const getShitRanking = (strings, ...values) => {
   const rate = values[0] || 0;
   let str = `★★★★★☆☆☆☆☆`;
   let start = 5 - rate;
   let end = 10 - rate;
   if(strings[0]) {
     str = strings[0].trim();
     start = (5 - rate) * (Math.ceil(str.length/10));
     end = (10 - rate) * (Math.ceil(str.length/10));
   }
   return str.slice(start, end);;
}
