Forum: JRuby ScriptingContainer UTF-8 encoding working differently in a Servlet

We are presently working on improving our UTF-8 support, and have had 
some
problems getting it to work properly.

The following code prints a different result when run from the command 
line
and when run from a Servlet (complete .java file available at
https://gist.github.com/4436025):

    ScriptingContainer container = new
ScriptingContainer(LocalContextScope.SINGLETHREAD);
    container.setCompatVersion(CompatVersion.RUBY1_9);
    container.runScriptlet("# encoding: utf-8\nputs ''");
    container.runScriptlet("# encoding: utf-8\nputs
''.bytes.to_a.inspect");

When run from the command line, the puts statements correctly print the 
pi
character and [207, 128].

When run from within a Servlet, the puts statements print the '?' 
character
and [63].

Anyone have any ideas as to why the code would behave differently in 
these
to contexts?

Thanks,
Ben Christenson
