[Cuis-dev] [IMPROV] Unicode Input in Editor

[Luciano Notarfrancesco]

Hi Hannes,
Yes, named characters can be extended, see UnicodeCodePoint
class>>#initializeNamedCharactersMap. However, they only can be input in
SmalltalkEditors, not general editors, since they were intended to be used
in code. Perhaps we should move the functionality from SmalltalkEditor to
Editor?
