We are using below Ant file to convert our native messages to unicode ones. Use it to produce a unicode-based resource bundle corresponding to your primary bundle. For detail info about this task see this page: ant.apache.org/.../native2ascii.html

build_convert.xml:

<project name="converter" basedir="." default="def">

<target name="def">

    <native2ascii encoding="UTF-8" ext="_unicode.properties" dest=".">

        <filename name="Application_fa.properties"/>


    </native2ascii>
</target>

</project>

Running this ant, will produces a unicode file with the name of the original one (Application_fa.properties) augmented with _unicode (Application_fa_unicode.properties).


Then in your JSF pages use f:loadBundle tag like below:
<f:loadBundle basename="Application_fa_unicode" var="bundle" />

Now, you can access your messages in other tag using EL:
<h:outputLabel value="#{bundle['message1']}"/>

By following these steps, your problem will be solved.
