libidn contains more than IDNA2003 functionality, such as stringprep et al. Libidn2 contains only IDNA2008 functionality, so there cannot be a 1-1 mapping between the two libraries and libidn2 cannot replace libidn for the protocols which still rely on stringprep. Stringprep is an IDNA2003 requirement but some protocols such as XMPP rely on it. regards, Nikos _______________________________________________ devel mailing list -- devel@lists.fedoraproject.org To unsubscribe send an email to devel-le...@lists.fedoraproject.org
