How do I remove this symbol from the CSV file that is generated by Puppeteer? - node.js

Question

When I generate the CSV file each "item" output comes out with a  symbol. How would I go about removing this with my code. I tried to change it to utf-8 because I read that might be what's causing it. Any ideas? Example:
const products = await page.$$('.item-row');
Promise.all(products.map(async product => {
// Inside of each product find product SKU, it's human-readable name, and it's price
let productId = await product.$eval(".custom-body-copy", el => el.innerText.trim().replace(/,/g,' -').replace('Item ', ''));
let productName = await product.$eval(".body-copy-link", el => el.innerText.trim().replace(/,/g,' -'));
let productPrice = await product.$eval(".product_desc_txt div span", el => el.innerText.trim().replace(/,/g,' -'));
// Format them as a csv line
return productId + ',' + productName + ',' + productPrice + ',';
})).then(lines => {
// Write the lines to a file
fs.writeFileSync("products.csv", lines.join('\n'), 'utf-8');
browser.close();
});
});

There are probably better solutions, but the first thing that comes to mind to to change the string to an array with split() and then .map through and test for the à ascii code and change back to a string with join() like this:
const strToChange = 'My string with an à char';
const charWeDoNotWant = 'Ã'.charCodeAt();
const toFixArr = strToChange.split('');
fixedArr = toFixArr.map(char =>
char.charCodeAt() === charWeDoNotWant ? '' : char
);
const fixedStr = fixedArr.join('');
console.log(`String without Ã: ${fixedStr}`);
