The following (taken from http://www.catb.org/~esr/faqs/things-every-hacker-once-knew/) may be relevant here:
"The very earliest VDTs, like the ASR-33 before them, could form only upper-case letters. An interesting hangover from these devices was that, even though most VDTs made after 1975 could form lower-case letters, Unix (and Linux as late as 2018) responded to a login beginning with an upper-case letter by switching to a mode which upcased all input. If you create an account with this sort of login name and a mixed-case password, hilarity ensues. If the password is upper-case the hilarity is less desperate but still confusing for the user."
OT: In a former job, we had an HP-Ux server, that did have this "feature". And the fun with "special" characters like @ and # (erase), which were handled different between passwd and login... Fun times. Mvg, Guus
