[AS7-6860] jboss-dmr APIs are unable to parse swidish characters

JBossAS7.2  dmr-api's are unable to parse swidish characters .
Example:
========= Run the following CLI command which will fail:
[standalone@localhost:9999 /] /core-service=management/ldap-connection=ldap_connection/:add(search-credential=jboss@123,url=ldap://xx.xx.xxx.xx:389,search-dn="ou=\\u00E5\\u00E5
u00E5,dc=example,dc=com")


Ideally it should have generated the following configuration inside the server profile (standalone.xml)

&lt;outbound-connections&gt;
&lt;ldap name="ldap_connection" url="ldap://xx.xx.xxx.xx:389" search-dn="ou=ååå,dc=example,dc=com" search-credential="jboss@123"/&gt;
&lt;/outbound-connections&gt;
