About the Unicode class

Hi,

Does anyone know why there are so many class variables in Unicode and what they are used for?
Most of them have no sender.

EncodedCharSet subclass: #Unicode
instanceVariableNames: ''
classVariableNames: 'Cc Cf Cn Co Cs DecimalProperty GeneralCategory Ll Lm Lo Lt Lu Mc Me Mn Nd Nl No Pc Pd Pe Pf Pi Po Ps Sc Sk Sm So ToCasefold ToLower ToUpper Zl Zp Zs'
category: 'Multilingual-Encodings'

Thanks,
Christophe

A partial / incomplete / broken implementation of querying character properties, I'd guess.

See for instance:

There has been some work on Squeak by Levente in this area, maybe it's time to harvest...

Thanks nicolas for the information. It is in the Unicode class?

Thanks for your answers.

I also took a look in Squeak 5.0 but the implementation is also incomplete.

I think the best is to remove unused unicode character categories.
