CALL Failed:3706 (procedure with session character set UTF 8)

Dear all,

I am running a procedure under sql assistant using teradata.net connection and the session character set is ASCII ,the compile of the procedure and the call is done.

I changed the  session character set to UTF 8, the procedure is not working anymore,the compile is done but the call gave this error:

CALL Failed. 3706: Syntax error: expected something between the word 'BBR' and a string or a Unicode character literal.

Thanks
