root@b1:~# curl 📙.la curl: (3) Failed to convert 📙.la to ACE; string contains a disallowed character Yet, both link to libidn2: root@b1:~# ldd $(which wget) | grep idn libidn2.so.0 => /usr/lib/x86_64-linux-gnu/libidn2.so.0 (0x00007fc8ce5ba000) root@b1:~# ldd $(which curl) | grep idn libidn2.so.0 => /usr/lib/x86_64-linux-gnu/libidn2.so.0 (0x00007f295d476000) So maybe it's a bug in curl itself?
