You can insert foreign accents in your documents (up to and including Word 2003) by clicking on the Insert menu and choosing Symbol.
Make sure that the Font box: shows normal text and then select on the appropriate symbol and click on Insert.
If you have to use accents frequently in your work, you can assign them to a Shortcut key or to AutoCorrect. You can do this while you are in the Symbol dialog box as above.
