Ancestors: Collections-nice.572

Character changes
- introduced #encodedCharSet to access the EncodedCharSet of a character
- all methods use #encodedCharSet instead of (EncodedCharSet charSetAt: self leadingChar)
- #isAlphaNumeric uses the EncodedCharSet class's #isAlphaNumeric: method

  isTraditionalDomestic
  	"Yoshiki's note about #isUnicode says:
  		[This method] is for the backward compatibility when we had domestic
  		traditional encodings for CJK languages.  To support loading the
  		projects in traditional domestic encodings (From Nihongo4), and load
  		some changesets.  Once we decided to get rid of classes like JISX0208
  		from the EncodedCharSet table, the need for isUnicode will not be
  		necessary.
  	I (Andreas) decided to change the name from isUnicode to #isTraditionalDomestic
  	since I found isUnicode to be horribly confusing (how could the character *not*
  	be Unicode after all?). But still, we should remove this method in due time."
