How can PHP developers ensure that their JSON-encoded data remains intact when dealing with non-ASCII characters?

When dealing with non-ASCII characters in JSON-encoded data, PHP developers can ensure that the data remains intact by using the `JSON_UNESCAPED_UNICODE` flag when encoding the data. This flag prevents the Unicode characters from being escaped, preserving their original form in the JSON output. 

$data = ['name' => 'İstanbul']; // Non-ASCII character example
$json = json_encode($data, JSON_UNESCAPED_UNICODE);
echo $json;
