What best practices can be implemented in PHP code to handle special characters and escape sequences in CSV files for cross-platform compatibility?

Special characters and escape sequences in CSV files can cause issues when reading or writing files across different platforms. To handle this, it's recommended to use PHP's built-in functions like `fputcsv` and `fgetcsv` along with properly encoding and decoding special characters using functions like `utf8_encode` and `utf8_decode`. 

// Example of writing CSV file with special characters properly encoded
$csvFile = fopen('example.csv', 'w');
$data = ['Name', 'Special Character: ü'];
fputcsv($csvFile, array_map('utf8_encode', $data));
fclose($csvFile);

// Example of reading CSV file with special characters properly decoded
$csvFile = fopen('example.csv', 'r');
$data = fgetcsv($csvFile);
$data = array_map('utf8_decode', $data);
fclose($csvFile);

print_r($data);
