Bug description:
  The printf command in bash (builtin) and corutils /usb/bin/printf have an error in counting the length of a string, if a non-ascii character is involved.
  Example is the arrow - type Alt+I.

  Try the following commands:
  printf -v r "%-2s X\n" '→' ; echo ${#r} # prints 4
  printf -v r "%-2s X\n" ' ' ; echo ${#r} # prints 5

  
  The coreutils version of printf has the same misbehaviour.
