Misalignment of pinky output: lack of support of multibyte char

[Rodolfo Ribeiro Gomes]

Hello. I was translating coreutils 8.3 and testing it when I saw that
the pinky output was not fine:
$ pinky
Usuário Nome                 TTY      Ocioso Quando           Onde
rodolfo  Rodolfo Ribeiro Gom  tty7     03:07  2010-01-14 18:03 :0

So I tried to see it on english, and it is ok:

$ LC_ALL=en pinky
Login    Name                 TTY      Idle   When         Where
rodolfo  Rodolfo Ribeiro Gom  tty7     03:10  Jan 14 18:03 :0

I changed the char á from my string as I use UTF-8, and it becomes ok,
but not with a correct spell:

$ pinky
Usuario  Nome                 TTY      Ocioso Quando           Onde
rodolfo  Rodolfo Ribeiro Gom  tty7     03:10  2010-01-14 18:03 :0
