Storing everything as Unicode is not a good idea, actually. First,
Unicode tends to consume more storage space than other character
sets. For example, UTF-8, one of the most commonly used encoding for
Unicode consumes 3 bytes for Japanese characters, while SJIS only
consumes 2 bytes. Second, a round trip converison between Unicode and
other character sets is not always possible. Third, sorting
issue. There is no convenient way to sort Unicode correctly.
