For Windows, jr8.bat runs the example, but
before you to this, edit, if necessary, the line
set JRUBY_JAR=c:\dl\jruby-complete-1.7.23.jar
in jr8.bat to wherever your JRuby-Complete file is located. To compile and run it with two separate jar files, simply execute
jr8
To compile and run it with one combined jar file, execute
jr8 Y C
Running the application will cause all kind of (mostly nonsense) text to be written to the standard output, the only purpose of this being that you can relate the produced text to the corresponding places in the program. By the way: If you run it in a Windows command console - which you most likely will -, the batch file sets the codepage to 1252 and some characters - those which are not defined in this codepage - are displayed as question marks in the standard output. This is not a bug, but expected behaviour.
The example also creates a file ucout.txt, which
contains a short UTF-8 encoded text. If you look at the text with your editor
and can't read it, even though you have set your editor to UTF-8, it means
that the editor font doesn't contain these characters. I usually set my text
editor font to MS Mincho to ensure that these characters are displayed
correctly, but be aware that, for
historical reasons,
MS Mincho displays the backslash (\) as ￥!
