utf 8 - JPA utf-8 characters not persisted -

i have simple web application use jpa.

i have entity called blogentry.

when submit new blogentry, when debug application see utf8 characters fine.

for example

em.persist(entity); 

in line, if debug example:

entity.gettitle() 

i can successfuly see utf-8 characters in ide. ( ğğ, or çç )

also, database has utf8 collation , can insert utf-8 characters fine sql using "insert into..."

however, jpa, characters persisted ????

why might be?

regards.

here persistence.xml:

<?xml version="1.0" encoding="utf-8"?> <persistence xmlns="http://java.sun.com/xml/ns/persistence" version="2.0">     <persistence-unit name="persistence">         <provider>org.hibernate.ejb.hibernatepersistence</provider>         <class>com.tugay.blog.core.model.blogentry</class>         <properties>             <property name="javax.persistence.jdbc.driver" value="com.mysql.jdbc.driver"/>             <property name="javax.persistence.jdbc.url" value="jdbc:mysql://localhost:3306/blogdatabase"/>             <property name="javax.persistence.jdbc.user" value="root"/>             <property name="javax.persistence.jdbc.password" value="aabbccdd"/>         </properties>     </persistence-unit> </persistence> 

use character encoding in property of persistence.xml file

<property name="javax.persistence.jdbc.url"     value="jdbc:mysql://localhost:3306/blogdatabase?useunicode=yes&amp;characterencoding=utf-8"/>
