& is the character reference for "An ampersand". ¤t; is not a standard character reference and so is an error (browsers may try to perform error recovery but you should not depend on this).

The only way that the & should be showing on the page is if you're double encoding the ampersand character (so the source of the page would be showing &). This could be caused by either storing the character already HTML encoded or you're using <%: (which HTML encodes everything for you automatically) instead of <%= in your View.
