What is the best practice for replacing Unicode characters with standard characters in PHP?

When dealing with Unicode characters in PHP, it may be necessary to replace them with standard characters for various reasons such as normalization or compatibility with certain systems. One common approach is to use the `iconv` function in PHP, which can convert strings between different character sets, including Unicode and standard character sets. 

// Input string with Unicode characters
$inputString = "Héllø Wørld";

// Replace Unicode characters with standard characters
$standardString = iconv('UTF-8', 'ASCII//TRANSLIT', $inputString);

// Output the standard string
echo $standardString;
