As matter of fact it does, otherwise characters would be the
same and we would not have this conversation at all. String
can be equivalent and not equivalent at the time, because there
are different equivalent relations. Finally, what HFS+ does
is even not normalization. In the technote, Apple explains
that they decompose some characters but not others for better
compatibility. So, you see, there is a PROBLEM here.


It is not about byte stream. After all, if it were UTF-16 instead
of UTF-8, it would be one to one conversion for each character.
So, what gets corrupted by HFS+ are Unicode *characters*.


I don't say they do that without *any* reason, but I suppose all
Apple developers in the Copland project had some reasons for they
did, but the outcome was not very good...


Not true. You lose the original sequence of *characters*.
