JavaScript:

To convert Unicode to ASCII in JavaScript, you can use the String.prototype.normalize() method followed by replace() method to remove or replace any non-ASCII characters.

Example:

1
2
3

const unicodeString = "Héllø Wörld";
const asciiString = unicodeString.normalize('NFD').replace(/[̀-ͯ]/g, '');
console.log(asciiString); // Output: Hello World

PHP:

To convert Unicode to ASCII in PHP, you can use the Transliterator::transliterate() function from the Transliterator class.

Example:

1
2
3
4

$unicodeString = "Héllø Wörld";
$transliterator = Transliterator::create('NFD; [:Nonspacing Mark:] Remove; NFC');
$asciiString = $transliterator->transliterate($unicodeString);
echo $asciiString; // Output: Hello World

Make sure to have the intl extension enabled in your PHP configuration to use the Transliterator class.
