(new patch)
/h/d/adduser $ sudo adduser фффффффффффффффффффффффф
adduser: Usernames must be no more than 32 bytes in length;
note that if you are using Unicode characters, the
character
limit will be less than 32.
In the 3.121, the IEEE check will squash it.
In 3.22:
~/h/d/adduser $ sudo adduser фффффффффффффффффффффффф --allow-all-names
Allowing use of questionable username.
Adding user `фффффффффффффффффффффффф' ...
Adding new group `фффффффффффффффффффффффф' (1023) ...
groupadd: 'фффффффффффффффффффффффф' is not a valid group name
adduser: `/sbin/groupadd -g 1023 фффффффффффффффффффффффф' returned
error code 3. Exiting.
so, not ideal, but it does error.
