Logging in with all capitals could switch the entire session to all-caps mode

What’s more weird is that I tried logging in onto my Gentoo 2004.3 Linux system using all capitals and, to my surprise, the whole session switch to an all-caps mode: the output of the “ls” command, even the “vi” editor.

While reading the UNIX-HATERS Handbook, I read the following phrase:

No, those were the real days of computing. And those were the days of Unix. Look at Unix today: the remnants are still there. Try logging in with all capitals. Many Unix systems will still switch to an all-caps mode. Weird.
