I've been trying use the built-in RSS widget with a current blog but every time I refresh the Dashboard after saving the feed information, the widgets disappears from the Dashboard sidebar. I've tried adding two different feeds. I never had this issue with another older blog (3.1 version). Does anyone know what is going on and how it can be fixed? Thanks!

OK, I've found out that if I removed Chinese characters from the feed titles, the RSS widget works. I've also discovered that my blog post headings will also not display Chinese characters, whereas they display just fine in the older blog. This is all very strange. Any ideas?
