Google Calender HTML Text in Calender

Hello, i’m try the EM client with Google. When i create a new Calender Entry it looks like the picture. When somebody else read it in thunderbird or in google calender android. Why is this?

You can change this option in your account settings. Go to Menu > Tools > Accounts and click on the GMail account. If you go to the Calendar tab you can disable HTML in the description.

Thanks that works.
