Not quite. IRIs are more than just IDN, as section 2.1 of RFC3987 says:

    IRIs are defined similarly to URIs in [RFC3986], but the class of
    unreserved characters is extended by adding the characters of the UCS
    (Universal Character Set, [ISO10646]) beyond U+007F

In order to work, you need to convert the IRI to a URI and that involves
knowledge (mostly character encoding) that curl doesn't have. See section 3.1
in the RFC3987: https://tools.ietf.org/html/rfc3987#section-3.1
