Thanks all. My current understand is such: Latin1 explicitly gives no semantics to several byte values (for example 0x81), but acknowleges that other standards will define their semantics. Unicode provides code-points with equally-undefined semantics so that these bytes can pass through without change. This allows a byte-level system using control codes in those ranges to interact with a unicode-aware system, without loss of information.
Does that summarize well?
