Percy, as an admin and developer off an internal bug tracking tool that has a web based gui (easier then writing an app that would have to run on UNIX, LINIX, Apples, and Windows), we've run into text display issues as well. We went to using UTF-8 as our company is multinational and needs to support many languages. There is no solution that will solve this display issue as there are many competing encodings that are mutually exclusive of one another. The example you pulled from the "God's plan ..." thread title is probably using a character from the extended ascii encoding which won't display properly in UTF-8.
