A sample of pages with the issue can be found under:
www.limaeasy.com
If you have a look at the main navigation on the left, go to Peru Info / Peruvian Personalities / José Quiñones (the 4th one...). If you actually open that particular page, you can see right in the header that the "é" and "ñ" are displayed corectly in the text.
Appreciate your comments!
