Artifacts Displayed in Email from Facebook

I’m wondering why these strange, cross-like code artifacts appear in mail received from Facebook.  I’m using eMC 7.0.279430, downloaded just the other day.

Advice appreciated!

I have used EM Client for over a Year.  I will repeat this suggestion in other other topics to help others avoid error problems as well.

Uninstall any Registry Optimizers/Cleaners that are standalone or included in other programs. Registry Optimizers/Cleaners can and do break programs by altering or removing necessary Keys and Values, destroying the proper functioning of many third party programs i.e. Browsers, email clients, VoIP, etc.

If you are using CCleaner then stick with the Cleaner feature but leave the Registry cleaner alone.
