After days trying finally found something to fix special characters mail headers problem:
I deleted line 271 $tmp = htmlentities($tmp, ENT_QUOTES, 'UTF-8');
and line 723 $subject = '=?utf-8?B?' . base64_encode($subject) . '?=';
now working perfect.
Please try and report if there are any side effects.
