@uma.s please don't forget there is a second phpmailer class under cron/class.phpmailer.php. This would be a good opportunity to get rid of that duplication. If not, at least do the same fix over there.

@ruben.estrada Yes! Even i noticed this and made relevant changes on Charset, But the workflows emails didn't capture the follow. Even workflows are handled through Emails class.phpmailer.php. So reverted the changes made on cron.

@uma.s so deleting cron/class.phpmailer.php wouldn't be an option? why have a dead class in the code base?

@ruben.estrada That's right! But we need to verify again all the possible case scenario to check if it's been used else where before deletion, will do it.

Great @uma.s , thanks!
