[Cuis-dev] [Ann] Unicode support in TextEditors, Files and Smalltalk code

[Juan Vuletich]

Hi Folks,

I've just pushed the updates needed to enable UTF-8 Unicode in editors, 
files and source code. This means that letters in any alphabet can be 
used in identifiers (variable and class names, selectors), literals, 
etc. Additionally, any math symbol in Unicode can be used in binary 
selectors.

Updating your image should not involve risk, as it is not activated by 
default. This means that editors still edit String using Character, and 
code is saved in StandardFileStream.

But the new code is very new, and hasn't been used for long. So, please 
play with it in throw-away images, where losing stuff is not a problem. 
To activate it, evaluate `TextModel useUtf8Editors`.

Please share your experience, and report any bugs or problems you find.

Enjoy!
