Ever wondered why our feed from The Register seems to always end with a question mark? Well, it appears as though they use special characters to show their ellipses (you know, the three dots "...", but they use just one character to represent that), which appears as a question mark to browsers... well, at least to most browsers. I would imagine browsers that use different localization encodings might display it properly.
It's not a very high priority, but the problem has been noted. I'll do my best to find a solution as soon as I can.
