Impex Config file
 

I just compared the config file included in the actual impex and the one I used 2 years ago when I imported my forum datas into vBulletin 3.69 at that time.
Both are almost the same exept one line that has disappeared:

2 years ago we had this at the end of config file:

Code:
define('use_utf8_decode', true);
Was it forgotten or is it normal?
