Character Encoding error when validating my site.

The character encoding specified in the HTTP header (utf-8) is different from the value in the <meta> element ( utf-8)

Where is the encoding sourced from in the theme?

I have found

<meta charset="
<?php bloginfo( 'charset' ); ?>
" />

But where does this come from? Somewhere there is an extra space being added.

Many thanks!
