What potential issues can arise when using utf8_decode() to decode JSON data in PHP, as seen in the provided code snippet?

Using utf8_decode() to decode JSON data in PHP can lead to problems if the JSON data contains characters that are not encoded in ISO-8859-1. This can result in data loss or corruption. To solve this issue, it is recommended to use json_decode() with the JSON_UNESCAPED_UNICODE flag to ensure that all Unicode characters are properly decoded.

// Fix for decoding JSON data with Unicode characters
$jsonData = '{"name": "Jürgen"}';
$decodedData = json_decode($jsonData, true, 512, JSON_UNESCAPED_UNICODE);

print_r($decodedData);
