When I designed my website 8 years ago I never thought that foreign people would register. Most of my users are from the US, Canada and Australia, however, there is a good number from other countries too. Some of their names, obviously, are not stored correctly in the DB because of the different characters that are used. I've done some research and switching to utf-8 is no small job. I'm wondering if it's worth the time and expense to implement. Anyone care to comment on their migration experience?

Thanks!
