Are there any potential pitfalls or limitations when using utf8_decode() and utf8_encode() functions in PHP for character conversion?

When using utf8_decode() and utf8_encode() functions in PHP for character conversion, one potential pitfall is that they only work with UTF-8 encoding. If the input string is in a different encoding, these functions may not produce the desired output. To avoid this limitation, it is recommended to use mb_convert_encoding() function, which supports a wider range of character encodings. 

// Example code snippet using mb_convert_encoding() for character conversion
$inputString = "Some text in a different encoding";
$convertedString = mb_convert_encoding($inputString, 'UTF-8', 'original_encoding');
echo $convertedString;
