  *sigh*  You cannot use them today if they are not assigned today.

  Well, the tables do not vary with the language processor, and if the
  tables change, chances are pretty damn small that you would suddenly
  notice and need any of the new characters.  Or do you code in futhark?

  This is highly misleading and uselessly inflammatory.

  This situation is quite similar to driving your car across city limits in
  the U.S.  The precise set of laws and regulations that determine the
  totality of allowable behavior changes not only from city to city, but
  they may be changed as you drive through a particular jurisdiction!
  Yikes!  You may enter the city limit a law-abiding citizen and flee it a
  haunted criminal a few minutes later, without doing a thing!  How can
  anyone possibly deal with this unpredictable randomness?  The Uniform
  United States Code is unworkable!  Democracy and rights and constitutions
  and procedures be damned, it is impossible to ascertain that you are a
  law-abiding citizen and you must fear the police at all times, as you may
  have broken a law that has just changed underneath you.  Not only are the
  police potentially after you, other drivers may be phoning the police
  about you as you slowly drive past them.  "Cell phone" just got a new
  meaning!  The fear, the suspense, the sheer _angst_ of the American
  driver is such a problem that we must shut down the legislative process
  and make changes in laws and regulations only at midnight on March 15,
  thirty minutes before and after which it would be illegal to be inside a
  car or less than 100 meters from any vehicle.  (Yes, we will convert to
  metric, too, just to be extra evil.)

  Or you can just drive you car through the city blissfully ignorant of all
  the _specific_ laws and regulations because the system is sufficiently
  stable and sane that these things do not actually ever happen.  You may,
  however, be a law-abiding citizen in one jurisdiction and a criminal in
  the next.  Did that frighten your socks off, or what?

  But if you live on the Unicode Fringe, I think you ought to be paranoid,
  as you have a criminal character and may be guilty of a capital crime.

  Please pardon the lack of respect for your hysterical opinion.

  This I appreciate in return, however.
  In a fight against something, the fight has value, victory has none.
  In a fight for something, the fight is a loss, victory merely relief.
