My first guess is that the file's encoding doesn't match your locale.
Do you have a non-ASCII locale set?  You can check with:

  $ locale
  LANG=en_US.UTF-8
  LC_CTYPE="en_US.UTF-8"
  LC_NUMERIC="en_US.UTF-8"
  LC_TIME="en_US.UTF-8"
  LC_COLLATE=C
  LC_MONETARY="en_US.UTF-8"
  LC_MESSAGES="en_US.UTF-8"
  LC_PAPER="en_US.UTF-8"
  LC_NAME="en_US.UTF-8"
  LC_ADDRESS="en_US.UTF-8"
  LC_TELEPHONE="en_US.UTF-8"
  LC_MEASUREMENT="en_US.UTF-8"
  LC_IDENTIFICATION="en_US.UTF-8"
  LC_ALL=

Although you can obviously have a different preferred language or
Unicode-capable encoding.  What you don't want is:

  # locale
  LANG=
  LC_CTYPE="POSIX"
  LC_NUMERIC="POSIX"
  LC_TIME="POSIX"
  LC_COLLATE="POSIX"
  LC_MONETARY="POSIX"
  LC_MESSAGES="POSIX"
  LC_PAPER="POSIX"
  LC_NAME="POSIX"
  LC_ADDRESS="POSIX"
  LC_TELEPHONE="POSIX"
  LC_MEASUREMENT="POSIX"
  LC_IDENTIFICATION="POSIX"
  LC_ALL=

If that's not the problem, could you attach the troublesome message?
Or a minimal example derived from the troublesome message?

Cheers,
Trevor
