UTF-8 printf string formating problem

[Jan Novak]

Hello,
printf string format counts bytes instead of chars, which leads to broken 
output ... just try this:
(/usr/bin/printf is broken too)

$ echo $LANG
us_US.UTF-8

$ printf "|%4s|\n" "aa"
|  aa|

$ printf "|%4s|\n" "áá"     (chars are a-acute)
|áá|

expected output:
|  áá|

IMHO this is a big bug, because it breaks any non ASCII chars formating.
