Answer by user13366325 for String length in bytes in JavaScript

I'm checking the length with :

const str = "🌧as%20😈"const len = new URL(str.replace(/%[A-F0-9]{2}/g, "..."), "https:$").pathname.replace(/%[A-F0-9]{2}/g, "-").length - 1console.log(len) // 13

when i (try to) verify if a directory name is less than 180 characters
