  60 function converts a lower-case letter to the corresponding
  61 upper-case letter.

  66 .Fn towupper_l
  67 function may be passed a locale directly. See
  68 .Xr xlocale 3
  69 for more information.
  70 .Sh RETURN VALUES
  71 If the argument is a lower-case letter, the
  72 .Fn towupper
  73 function returns the corresponding upper-case letter if there is
  74 one; otherwise, the argument is returned unchanged.
