Java: InetAddress.getLocalHost();抛出 java.net.UnknownHostException

Question

我有一个问题运行我的 Java 应用程序：执行以下行时，它抛出异常：

InetAddress.getLocalHost();

抛出以下异常：

java.net.UnknownHostException: ????????: ????????
at java.net.InetAddress.getLocalHost(InetAddress.java:1506)
at main.Main.main(Main.java:23)
Caused by: java.net.UnknownHostException: ????????
at java.net.Inet6AddressImpl.lookupAllHostAddr(Native Method)
at java.net.InetAddress.lookupAllHostAddr(InetAddress.java:929)
at java.net.InetAddress.getAddressesFromNameService(InetAddress.java:1324)
at java.net.InetAddress.getLocalHost(InetAddress.java:1501)

我知道这是我本地机器的问题，因为它可以在我的虚拟机和其他设备上运行。我正在使用 Windows 10 并且我的主机文件是默认文件（未编辑）。问号是什么意思？我可以尝试解决这个问题吗？

我知道问题出在哪里了：我的主机名由西里尔字母组成。 Discord 上的一位用户是这样向我解释的：

this seems to be a limitated at the C function getaddrinfofunction [12:14] which does make sense, considering cyrillic isn't a valid DNS name, so it's following RFC. [12:14] (even though hostname != dns name techically, but nuances). [12:15] RFC 952 and RFC 1123 have details info on it
