 libidn2 could do that if they felt it appropriate.

 Not intending to start a debate here, so long story short, the same could
 be said about the backport of OpenSSL 1.1 support to Qt4, or even the
 whole `port:legacy-support`. Or indeed to patching the code to use libidn2
 instead of libidn ;)

 In that light, what do we do with this ticket now? Is there any reason to
 patch code to use libidn2 instead of libidn if we're going to be keeping
 both versions anyway?
