I made UChar and UTF-8 two different modules because,

  * Char and String are different modules, and I want to make unicode
  modules similar to the string API of stdlib as far as possible, and

  * Users, or eventually we, may provide other Unicode string (UTF-16,
    UCS-4, BOCU, or whatever).  Making UTF-8 an independent module
    would make changing Unicode string implementation easier.

If nested modules are acceptable, we can pack them into one module, of
course.

Is it better to define its own exception than to use invalid_arg?
Currently, UTF-8 module don't do bound checking itself for the
performance reason.  Is it better to do bound checking in UTF-8, and
raise its own exception other than Invalid_arg?
