Binary data must be put away from restored text, and must be included but escaped in the section where a report of the original data goes. This affects the occurrences of escape secuences from the original file, which then must be escaped again. It is expected that these sequences are not grabbed up from the way the algorithm strips down regexes. Check.

Similarly, control characters must be accepted at the parsing phase, stripped off from the restored text and escaped for the original data section.
