This is a sticky post. There are a few things to verify: The sticky post should be distinctly recognizable in some way in comparison to normal posts. You can style the .sticky class if you are using the post_class() function to generate your post classes, which is a best practice. They should show at the very top […] +

Putting special characters in the title should have no adverse effect on the layout or functionality.
