What are the potential pitfalls of trying to convert strings from ISO-8859-1 to UTF-8 in PHP, and how can they be avoided?

When converting strings from ISO-8859-1 to UTF-8 in PHP, potential pitfalls include incorrect character mapping leading to data corruption and loss of information. To avoid these issues, it's important to use the mb_convert_encoding function with the correct parameters to ensure accurate conversion.

$isoString = "Hello, world!";
$utfString = mb_convert_encoding($isoString, 'UTF-8', 'ISO-8859-1');

echo $utfString;
