Unicode characters (Arabic letters) show up as question marks in IDE console - jsf

Question

I am using JSF 2.0 and I have text field as
<h:form>
<h:inputText value="#{myBean.myValue}" />
<h:commandButton value="Submit" action="#{myBean.printMe()}" />
</h:form>
public void printMe() {
System.out.println("first line==" + myValue + "==");
System.out.println("second line==يشسيبشسيبشسيبشيس==");
}
When I run this project and enter يشسيبشسيبشسيبشيس in textbox, in IDE console I see as below.
INFO: first line==????????????????==
INFO: second line==????????????????==
Any idea why this is happening?

Answer 1

This is caused by using the wrong console encoding.
The line
System.out.println("My Data is " + fullName);
prints to the standard output (stdout). You need to configure it to use UTF-8 as well. Assuming that you're using Eclipse, then you need to change the stdout encoding to UTF-8 by Window > Preferences > General > Workspace > Text File Encoding.
If you're using Netbeans, which I can't answer from top of head, head to this answer: hebrew appears as question marks in netbeans which contains a link to this Netbeans Wiki which mentions the following:
To change the language encoding for a project:
Right-click a project node in the Projects windows and choose Properties.
Under Sources, select an encoding value from the Encoding drop-down field.

Unrelated to the concrete problem, those lines in the filter are unnecessary
res.setCharacterEncoding("UTF-8");
res.setContentType("text/html;charset=utf-8");
They defaults in case of JSF2/Facelets to proper values already. Remove those lines.

If the data comes from a DB, please check the field datatype is nvarchar.
