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
Scanner>>typeTableAt: aCharacter
	^typeTable at: aCharacter charCode ifAbsent:[#xLetter]

I would tend to restrict this to
	^typeTable at: aCharacter charCode ifAbsent:[
		aCharacter isLetter
			ifTrue: [#xLetter]
			ifFalse: [#xIllegal]]

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 ?
