I don’t know Hindi, but the next $ charsArray contains most emails from well-known languages (including Hindi). (This is from the core of Laravel).
function ascii($value, $charsArray) { foreach ($charsArray as $key => $val) { $value = str_replace($val, $key, $value); } return preg_replace('/[^x20-x7E]/u', '', $value); } $charsArray = [ '0' =>

So, you need to insert the Hindi name in the function, and it will return the English equivalent of the letters of the name (not a translation).
$englishName = ascii($indianName, $charsArray);
If $ charsArray does not contain all the letters you need, or you just need to configure it, you can easily add the English letters / s to the $ charsArray key, and their Hindi / corresponding array (value). And you're done!
