Pasting text with a hexadecimal numeric character reference, like ä, into a literal block in OE, will truncate the text from the point of the reference.

Steps to reproduce:

1. Create any content object with an XML block (example, folder, article)
2. Add a literal block into it
3. Paste text like the following: Something ä Something else
4. Publish, and access your content

The text will break on ä (ä character).
