We plan to register IDNs "soon" in ".fr". Our legacy software is in Perl and Java. I need IDN "free as in free speech, not free as in free beer" implementations for both.
For Perl, I could write a XS to the excellent GNU libidn or to MDNkit but I hope someone else did it before the lazy guy I am. The implementation in <URL:http://www.imc.org/nameprep/> is quite outdated and I wonder if I can reasonably use it?
