I just tried to use the filter on a clean jessie system with nginx
1.6.5+deb8u4:

apt-get install nginx-full curl
rm /etc/nginx/sites-enabled/default
cat <<EOF > "/etc/nginx/sites-enabled/hello"
server {
	listen 80 default_server;
	root /srv/dir;

	sub_filter 'Hello' 'Goodbye';
	sub_filter_once off;
	sub_filter_types *;
}
EOF

nginx -t
nginx -s reload

mkdir /srv/dir
echo "Hello world!" >/srv/dir/hello.txt

curl localhost/hello.txt
Goodbye world!


Perhaps there is something else that is wrong with your general configuration.
