Having run into string-related problems myself in my iochain project,
I'm thinking about character encodings again. (I don't like the term
character set. It ought to mean something different from its common
usage. UTF-8 and UTF-16 aren't character sets.)

Why on earth would you change the character set of a string at runtime?

Robert O'Cahallan (roc of Mozilla) recently blogged a bit about strings.
Mozilla is a project that has a lot of experience with strings, so I put
quite some weight on his opinion.
