Please check here, wether setlocale is successful. Otherwise an error should be logged, describing possible issues. Maybe the 'C.UTF-8' string should be configurable.

This trouble solving if MODX Setting "locale" is correct encoding for current server environment.
Now I don't run setlocale manually, just log about encoding if function pathinfo return not what was expected

$pathinfo = pathinfo($oldFile);
$directory = preg_replace('/[\.]{2,}/', '', htmlspecialchars($pathinfo['dirname']));
$name = htmlspecialchars($pathinfo['basename']);
$oldFile = $directory.DIRECTORY_SEPARATOR.$name;

$newFile = $this->getProperty('name');
$pathinfo = pathinfo($newFile);
$directory = preg_replace('/[\.]{2,}/', '', htmlspecialchars($pathinfo['dirname']));
$name = htmlspecialchars($pathinfo['basename']);
$newFile = $directory.DIRECTORY_SEPARATOR.$name;
setlocale(LC_ALL,$oldlocale);
$success = $this->source->renameObject($oldFile, $newFile);

if (empty($success)) {
$msg = '';
