[whatwg] Web Addresses vs Legacy Extended IRI (again)

[Kristof Zelechovski]

It is not clear that the server will be able to correctly support various
representations of characters in the path component, e.g. identify accented
characters with their decompositions using combining diacritical marks.  The
peculiarities can depend on the underlying file system conventions.
Therefore, if all representations are considered equally appropriate,
various resources may suddenly become unavailable, depending on the encoding
decisions taken by the user agent.
