Steps to reproduce:

• Go to Blogs Admin (Content > Blogs)
• Add a new Blogs entry with a link in its body. The link must have non urlencoded invalid characters (e.g. "http://www.sou.gov.se/wp-content/uploads/2017/06/├ľvergripande-modellf├Ârslag-180104.pdf").
• Save blogs entry

Expected: Either an error is signaled or the URL is urlencoded and saved correctly.
Actual: No error shows. The link's href attribute is empty.
