This is a shot in the dark, but my first guess is that (since you mentioned "international) is that this could be a text encoding issue in the browser. From the menu bar, click View>>Text Encoding, then choose Unicode (UTF-8). This should also be your default choice within your browser preferences (usually found in the Appearance or Fonts preference panel depending on your browser of choice). After making the change, reload the page to display any changes to font/character display.
It definitely won't hurt. It will also ensure that whenever you run into foreign language characters or any other non-American English characters, you should see your pages displayed properly (as long as there is a proper char-set in the heading) and you'll avoid seeing "gibberish."
