I found a solution via another way. (don't remember which website I found it) See code below. This code will export my file in UTF-8-BOM encoding.

DECLARE @OLE            INT 

EXECUTE sp_OACreate 'ADODB.Stream',  @OLE OUTPUT

DECLARE @Text XML
SET @Text =  N'This is the 测试测试 test string';  --(SELECT TOP(1) [xml] from VW_WARP_LEVERANCIERS_XML)     
DECLARE @Converted NVARCHAR(MAX)
SET @Converted = CONVERT(nvarchar(MAX), @Text)

EXECUTE sp_OASetProperty             @OLE,    'Type',             2                           --1 = binary, 2 = text
EXECUTE sp_OASetProperty             @OLE,    'Mode',             3                           --0 = not set, 1 read, 2 write, 3 read/write
EXECUTE sp_OASetProperty             @OLE,    'Charset',          'UTF-8'                     --'ISO-8859-1'
EXECUTE sp_OASetProperty             @OLE,    'LineSeparator',    'adLF'
EXECUTE sp_OAMethod                  @OLE,    'Open'  
EXECUTE sp_OAMethod                  @OLE,    'WriteText',        NULL,       @Converted      --text method

--Commit data and close text stream
EXECUTE sp_OAMethod                  @OLE,    'SaveToFile',       NULL,       'd:1.txt', 2   --1 = notexist 2 = overwrite
EXECUTE sp_OAMethod                  @OLE,    'Close'
EXECUTE sp_OADestroy                 @OLE

EXECUTE sp_OADestroy @OLE
