Hi, I was the original contributor of IDN2 support. I have to agree IDN2 does filter underscores out.
On Fedora 25: $ idn2 --version idn2 (libidn2) 2.0.2 $ idn2 -l _xmpp-server._tcp.domain.com xmpp-server.tcp.domain.com Not even transitional mode helps $ idn2 -T _xmpp-server._tcp.domain.com xmpp-server.tcp.domain.com But older IDN works fine $ idn --version idn (GNU Libidn) 1.33 $ idn _xmpp-server._tcp.domain.com _xmpp-server._tcp.domain.com I will have have to ask why would it do that. Another question is whether SRV records should be formatted by libidn2 when they will not be displayed to the user. I think it should affect only logs but not served names themselves.
