strings command printing some extra characters

I am trying to capture mysql traffic using tcpdump and converting it to text using strings command, but while capturing mysql traffic, I am getting some extra character at the end of each character. I am unable to figure out the reason. e.g. CREATE TABLE foo1.foo (id INTEGER, name VARCHAR(20))H> As you can see, there is H> at the end of query. Can someone help me in solving this. **Edit:** I am running the following command to capture the traffic. $ sudo tcpdump -i any -s 0 -l -w - dst port 3306 | stdbuf -i0 -o0 -e0 strings -12
