What are some common pitfalls to avoid when working with encoded data in PHP?

One common pitfall when working with encoded data in PHP is failing to properly handle character encoding. To avoid issues with character encoding, always ensure that you are using the correct encoding functions such as `mb_convert_encoding()` or `iconv()` when working with strings in different encodings. 

// Example of converting a string to UTF-8 encoding
$encodedString = "Some encoded data";
$utf8String = mb_convert_encoding($encodedString, 'UTF-8');
echo $utf8String;
