This week's book giveaway is in the OCAJP 8 forum. We're giving away four copies of OCA Java SE 8 Programmer I Study Guide and have Edward Finegan & Robert Liguori on-line! See this thread for details.
Surely this is no dumb question. I don't have much experience in this area, but I do know a couple of things (and hopefully bringing this thread to the top of the pile again might help to grab the attention of someone with some more expereince). Let's clarify your question. By "extended" do you mean The Extended ASCII Codes?
I'm going to assume that you mean non-ASCII characters. I'm pretty sure the standard Java console is only capable of displaying ASCII characters (all 255 of them). AWT or Swing can be used to display an Unicode character provided that the appropriate font is installed on the user's machine. More information on Unicode can be found at http://www.unicode.org/ More information on the character sets that Java does support can be found in the standard API documentation: http://java.sun.com/j2se/1.4/docs/guide/intl/encoding.doc.html Are you getting any ideas?
