Unwanted output "Using Charset"

Unwanted output "Using Charset"

I am trying to get an output from a stored procedure in a file. But the
stored procedure outputs the charset 2 times
using default charset "UTF-8"
using default charset "UTF-8"
and then the output. How can i remove this from the output? Also the
output does not print the headers. Any idea why? I am using MSSQL with
FreeTDS. But i have no access to freetds.conf.
