Pasting text with numeric character references (decimal * or hexadecimal ä) into a literal block will be shown as their interpreted values. They should be shown literally (unless the literal block is a custom one which outputs its content without escaping).

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: *
4. Publish, and access your content

The text will appear as * and not as *

This affects 5.4, but not 5.3.
