I am trying to concatenate unicode in JavaScript and i'm getting this error "Invalid Unicode escape sequence". I have tried to search how to concatenate unicodes in javascript and i've seen many examples here on this site but nothing has worked for my code... I found something about using String.fromCharCode too but without a great example. So i could not figure it out.
So. Here is an example code
let test = "5000",
string;
let unicode = test.split()
for(let i = 0; i < unicode.length; i++) {
string += "\u003"+unicode[i]+"\uFE0F\u20e3";
}
console.log(string);
You are trying to concatenate \u003
before the item. Since it is not a unicode character, it is causing the error. Removing the problematic string should fix it.
Also, you have to provide string
a default value before concatenating. Otherwise, it is undefined
.
let test = "5000",
string = "";
let unicode = test.split('')
for (let i = 0; i < unicode.length; i++) {
string += unicode[i] + "\uFE0F\u20e3";
}
console.log(string);
