$input or $rInput?

[sody1981]

i think this is better code:
public function translateFromUtf8($input)
{
if ($input == null)
return $input;
if ($this->isRunningOnWindows()) {
if (is_array($input)) {
for($i = 0 ; $i < count($input);$i++)
$input[$i] = iconv('UTF-8', mb_detect_encoding($input[$i]), $input[$i]);

    } else
        $input = iconv('UTF-8', mb_detect_encoding($input), $input);
}

return $input;

}
