You want a NEWLINE stored in db, but you don't have that. You have a "/n" character that is automatically escaped when read back. What you should do is
A. store the string as
myEntity.MyStringInfo = "abcd/n";
Then when you fetch the data is presented as expected. Tip: when you store a NEWLINE it's not visible/readable in db text.
B. Or convert/transform/replace the fetched string to get what you want.
I'm not expert in string escaped characters, but few tests I did worked like I just said.
