EndNote tutorial

On Monday, professor forwarded me a mail of EndNote tutorial held today in the computer lab. As it's been 3-4 years since I used EndNote last time, I attended it as a revision. The tutor is Cheryl, a librarian specializes(?) in scientific area. The version of the software is ver8. Obviously it has upgraded times from which I used to use (ver.5) during my Master study in Taiwan. However, I can't see too many changes on the interface. The tutorial includes: building personal library, typing references (such as authors, articles, dates, etc), importing and inserting citations, and so on. Although these're totally nothing new to me, the tutorial was still a good revision. After that, I asked Cheryl a small question about authers' name - how to type those authers' name with strange characters (like French or German or whatever). Unfortunately she had no idea as well, and I was asked to let her know through mail if I found the way to do this. So, how should I solve this...?
