Some fixes for RWBinaryOrTextStream which was too agressive optimizing some paths. Also fixes Character>>codePoint: which has no reason to raise an exception for values > 256.
Don't know about the reason for such a limitation by just reading the diff... However, there was some insurance that a Character of value < 256 would be unique. Doesn't this matter?
#value: does this.

Does it mean #codePoint: is a low level (basic) creation message, private and not to be used except in special circumstances like creating the CharacterTable, while #value is the public API?
Or does it mean any code using the ANSI protocol #codePoint: wont' share the uniqueness property of #value:?
The category and comment made me think it was the latter, thus my question.
Nicolas
I don't understand. #codePoint: uses #value: so there is no difference.

Thanks for your patience, I just realized it...
