Please use word-wrap: break-word; in CCS rule for body in contents.css or your page css if you are using inline editor.

Chrome for example adds this style by default. For other browsers you need to add this rule manually.

CKEDITOR.addCss( 'body {word-wrap:break-word;' );
CKEDITOR.replace( 'editor' );
