Openfire: Offline UTF-8 encoded messages are saved wrong -



use openfire 3.9.3. mysql database uses utf8_persian_ci collation , in openfire.xml have:

...<defaultprovider>    <driver>com.mysql.jdbc.driver</driver>     <serverurl>jdbc:mysql://localhost:3306/openfire?useunicode=true&amp;amp;characterencoding=utf-8</serverurl>     <mysql>      <useunicode>true</useunicode>    </mysql> ....

the problem offline messages contain persian characters (utf-8 encoded) saved strings of question marks. example سلام (means hello in persian) stored , showed ????.

mysql not have proper unicode support, makes supporting data in non-western languages difficult. however, mysql jdbc driver has workaround can enabled adding 

?useunicode=true&characterencoding=utf-8&charactersetresults=utf-8

to url of jdbc driver. can edit conf/openfire.xml file add value.

note: if mechanism use configure jdbc url xml-based, need use xml character literal & separate configuration parameters, ampersand reserved character xml.

also sure db , tables have utf8 encoding.
