In reply to General comments about numerals:
@John (quadibloc): The user interface to those functions has to be via the application (or operating system api's or third party add-ons). The fonts themselves, no matter how intelligent can't and shouldn't provide the means of telling them what to do.
Why should font creators, create 17 different fonts (as they used to be forced to do) where ONE now suffices?
