+features:
+@itemize
+@item take care of IDN domains
+@item always provide the URI scheme in lowercase characters
+@item always provide the host, if any, in lowercase characters
+@item only perform percent-encoding where it is essential
+@item always use uppercase A-through-F characters when percent-encoding
+@item prevent dot-segments appearing in non-relative URI paths
+@item for schemes that define a default authority, use an empty authority if
+the default is desired
+@item for schemes that define an empty path to be equivalent to a path of
+@code{/}, use @code{/}
+@item for schemes that define a port, use an empty port if the default is
+desired
+@item all portions of the URI must be utf-8 encoded NFC from Unicode strings
+@end itemize")
