+1.17 Add support for IRIs
+
+ IRIs (RFC 3987) allow localized, non-ascii, names in the URL. To properly
+ support this, curl/libcurl would need to translate/encode the given input
+ from the input string encoding into percent encoded output "over the wire".
+
+ To make that work smoothly for curl users even on Windows, curl would
+ probably need to be able to convert from several input encodings.
