native IDN support on macOS #6
Description
From here:
On recent macOS versions, the getaddrinfo() function itself has built-in IDN
support. By setting the AI_CANONNAME flag, the function will return the
encoded name in the ai_canonname struct field in the returned information.
This could be used by curl on macOS when built without a separate IDN library
and an IDN host name is used in a URL.
