Error caused by call WideCharToMultiByte with cchWideChar = 0

Testcase:

$connectionInfo = [
    "UID" => 'php',
    "PWD" => 'test',
    "APP" => 'Test-App',
    "CharacterSet" => SQLSRV_ENC_CHAR,
    "MultipleActiveResultSets" => true,
    "Database" => 'tempdb',
];
$conn = sqlsrv_connect('127.0.0.1,1433', $connectionInfo);

$sql = "EXEC dbo.sp_executesql N'
    DECLARE @x nvarchar(max)
    SET @x = '''' -- empty string
    SELECT @x AS [Empty_Nvarchar_Max]
'";

$stmt = sqlsrv_query($conn, $sql, [], ["Scrollable" => 'buffered']);

$return = sqlsrv_fetch_array($stmt, SQLSRV_FETCH_ASSOC); // Fatal error: Severe error translating Unicode
