the only reason for upgrading to 2016 is the utf-8 encoding witch comes with it
meanwhile i tried another approach than succeeded:
set @xml=(select xml_data from FCSD.DBO.XmlImport)
set @xml_convert=cast(@xml as nvarchar(max));
IF OBJECT_ID('tempdb..##x') IS NOT NULL DROP TABLE ##x;
select @xml_convert AS x into ##x;
set @sql='bcp "SELECT x FROM ##x" queryout c:\1.xml -S '+@@servername+' -T -t -c -C 65001'
EXEC master..xp_cmdshell @sql
drop table ##x
