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

[Luciano Notarfrancesco]

Hi Juan,
I started using UTF-8 in my math project. I was surprised that I didn’t
have to search and replace the special characters that we were using before
Unicode support… I just filed-in my packages and then filed-out as UTF-8
without doing anything special. Tests pass, everything seems to be working
fine. Thank you!

One minor problem that I ran into is that now we cannot concatenate strings
with Text. In some printOns I was doing something like ‘ζ’, ‘0’ sub but now
I have to do ‘ζ’ asText, ‘0’ sub. Not sure if this change was intentional,
but it is reasonable to me, no need to “fix” it.

Also, look at the method Character>>#namedCharactersTable. Why is that the
arrows are shown as null glyphs? I’ll later update this method with all
Greek letters and some other useful symbols.

Thanks!
Luciano
