UTF-8 Encoding Problem

[vata2999]

I added following lines to standalone.xml after extensions tag . even in debug mode I can see it has been set

<system-properties>
<property name="org.apache.catalina.connector.URI_ENCODING" value="UTF-8"/>
<property name="org.apache.catalina.connector.USE_BODY_ENCODING_FOR_QUERY_STRING" value="true"/>
</system-properties>

System.getProperty("org.apache.catalina.connector.URI_ENCODING") // returns UTF-8

yet I still get this characters تایید مدیر before inserting object into database!

I also registered servlet character encoding filter

<web:character-encoding-filter encoding="UTF-8"
        override-client="true" url-pattern="*.seam" />

I can't think of anything else. is there something that I'm missing ?

PS : I'm using JBoss eap 6.2 (AS 7.3.0.Final)
