Problem with Greek characters on view page source

Hi,
I have the following problem and I do not know what to do. I've uploaded a site using opencart and journal theme and when I do right-click -> view page source, displays the Greek text I've entered with some strange words. See the printscreen. Please help

Thank you in advance

Well, according to the Image, the MEGA-MENU MIXED Extension is in greek language,
and this code can only be 'interpreted', if one uses greek language in an OC Installation.
So, better get in contact with the Seller of your 'customized' Installation, no-one else
would be able to, I assume. And if one uses Custom Paid Themes + Extensions, this place will
usually not cover such. So, next time, you'll come here, better read the rules before,
without exact DATA, on the OC Version used, as well as on Theme Versions and Extensions,
there is no way to assist.
