You are running into problems with whitespace in the command which needs to
be escaped.  It is splitting the -H argument into pieces.

I think you would get something if you executed it in the command, setting
x to the output of the command, but I don't think this would do you much
good here.

x=`curl -L -i -H 'Content-Type: text/html; charset=utf-8' host`
