UTF-8 Unicode SMS Scrambled

Hi all, Not able to send unicode message, receiving scrambled content. This issue is on production and I was able to reproduce on testing environment *INSERT Statement:* INSERT INTO `kannel`.`send_sms` (`sql_id`, `momt`, `sender`, `receiver`, `udhdata`, `msgdata`, `time`, `smsc_id`, `service`,

'@' missing in MO message.

We kannel is replacing '@' with empty in MO message. In kannel bearerbox log delivery_sm data_coding is set to 1. How to configure kannel to get '@' correctly in application end. Regards, Manas
