whois 和其他工具不适用于 IDN

Whois 和其他工具不适用于国际域名。这些名称无法正确转换为微不足道的代码。

$ whois ąćęłńóśźż.pl 
Incorrect domain name: ąćęłńóśźż.pl

我很确定这些工具曾经可以正常工作。IDN 的处理方式有变化吗？

这可能是什么原因？我该如何解决？这是语言环境问题吗？

whois对我而言在 16.04 上有效：

$ whois ąćęłńóśźż.pl

至于其他三个命令，作为一种解决方法，您可以执行sudo apt-get install idn然后使用它来进行翻译：

$ dig $(idn ąćęłńóśźż.pl)
