Attempt of creating forum topic/content discussion/whatever with non-English characters in message field leads to indefinite time of waiting for page to load on click of "Create Topic" button.
Steps to reproduce
1. Start discussion on any node (e.g. Data Dictionary)
2. Enter non en_us characters into "message" field.
3. Click "create topic" button
Topic with message in locale entered should be displayed
Browser starts loading page forever. Attempt to stop loading/navigate anywhere else leads to appearing of content discussion as standalone node. (See screenshot attached)
