JMS Receiver Channel sending Special characters from SAP PI!!

Hello Experts,

Greetings for the day!!!!

I have added the setting in the communication channel with 819 as CCSID and ISO-8859-1 parameter in the additional parameters section but ended in the same situation.Here are the below screen shots of the same.

Would request you to kindly help on the same so that i can proceed further with same.

Thanks in advance!!!

Many Thanks,
