What are some alternative methods in PHP for handling character encoding issues on Windows systems?

Character encoding issues on Windows systems can be handled by using the `mb_convert_encoding()` function in PHP to convert strings from one encoding to another. This function allows you to specify the input encoding, output encoding, and the string to be converted. By using this function, you can ensure that your strings are properly encoded and displayed correctly on Windows systems.

// Convert a string from one encoding to another
$inputString = "Hello, こんにちは";
$outputString = mb_convert_encoding($inputString, "UTF-8", "SJIS");

echo $outputString; // Output: Hello, こんにちは
