What are the potential pitfalls of using utf8_encode() in PHP when working with CSV files?

Using utf8_encode() in PHP when working with CSV files can potentially lead to data corruption or loss of special characters that are not supported by the UTF-8 encoding. To avoid this issue, it is recommended to use mb_convert_encoding() instead, which allows for more flexibility in handling different character encodings.

// Read CSV file with mb_convert_encoding() to handle different character encodings
$csvData = file_get_contents('data.csv');
$csvData = mb_convert_encoding($csvData, 'UTF-8', 'auto');
