My solution:
To show inline solution:
Change: public/class-email-before-download-public.php
Line: 108, add utf8 decode to title -> utf8_decode($links[$link->selected_id][‘title’])
To emails links:
Change: includes/class-email-before-download-process.php
Line: 167 add utf8 decode to $link->title = utf8_decode($title);
