welcome to the board!
\usepackage can only be used inside the preamble. Those commands will also be valid for the by \input included parts. Perhaps those external files are having a different encoding. You could post such a file as attachment here for us to examine.
now i use emacs, what do you mean when you ask if my input is in latin 1 encoding considering i cannot insert a \usepackage[latin1]{inputenc} in the input file
