Answer 1

This is a little more simple and more direct answer to the main question. the function below mimics the PHP approachs. Just in case if PHP extend this with their namespaces in the future, a test is first checked. Im using this water proof for any languages in my wordpress installs.

$str = mb_ucfirst($str, 'UTF-8', true);

This make first letter uppercase and all other lowercase as the Q was. If the third arg is set to false (default), the rest of the string is not manipulated.

// Extends PHP
if (!function_exists('mb_ucfirst')) {

function mb_ucfirst($str, $encoding = "UTF-8", $lower_str_end = false) {
    $first_letter = mb_strtoupper(mb_substr($str, 0, 1, $encoding), $encoding);
    $str_end = "";
    if ($lower_str_end) {
        $str_end = mb_strtolower(mb_substr($str, 1, mb_strlen($str, $encoding), $encoding), $encoding);
    } else {
        $str_end = mb_substr($str, 1, mb_strlen($str, $encoding), $encoding);
    }
    $str = $first_letter . $str_end;
    return $str;
}

}
