Oh, I just noticed there is a #xIllegal ... Not really used.
Using #xIllegal as default type would raise the question of what
character beyond ASCII can be considered a valid binary...
«¬±·»¿×÷ eventually are good candidates for example
Not sure about these ¢£¤¥§¶
My following question will be about
^typeTable at: aCharacter charCode ifAbsent:[#xLetter]
I would tend to restrict this to
^typeTable at: aCharacter charCode ifAbsent:[
but we might want some more extended binary characters...
And program with ideograms, not only letters...
Unless we restrict selectors to ASCII ?
Are non ASCII selectors in use ?
