What mapping you have in mind?

WideString>>at: index
	"Answer the Character stored in the field of the receiver indexed by
the argument."
	^ Character value: (self wordAt: index).

Character class>>value: anInteger
	"Answer the Character whose value is anInteger."

	anInteger > 255 ifTrue: [^self basicNew setValue: anInteger].
	^ CharacterTable at: anInteger + 1.

(Character classPool at: #CharacterTable) withIndexDo: [:ch :i | self
assert: (ch asInteger = (i-1))]

So, it is 1:1 correspondence between word, stored in wide string (self
wordAt: index),
and Character value, used for hashing. So, no mapping required.
