[Cuis-dev] UTF-8 Unicode editors

[Juan Vuletich]

Class StringUtf8 is a bytes object (like ByteArray). It implements 
#byteSize, #byteAt:, #byteAt:put:. #at: is rather expensive. It doesn't 
support #at:put:. It has several iteration messages in CodePoints. 
Performance seems OK for reasonably small stuff.

In any case, it is always possible to change the data structure, as long 
as it is polymorphic.

I haven't used it for Smalltalk source code yet, only for stand alone 
editors. Parser would see instances of UnicodeCodePoint, maybe mixed 
with Characters (for code points that fit in a Cuis Character).

So far this is experimental, so we can adapt it while we learn the 
details of what we need.
