Our latest symbol set may be our last, but maybe not. In 2 or 3
years, we may update our symbol set. This would cause problems
because Unicode is not allowed to change.
How good an idea is it to attempt to standardize a character encoding in
which it is expected that characters might still move around?
We will be using this symbol set for a long time, maybe forever. It's a
great idea to explicitly state that these are open standards for general
If we release a general coded character set, we can always release another
in the future, such as the x-iswa-2010. This would not be possible with
Unicode because it's written in stone (once it's written).
