Using character entities can be a fun part of your design! You can use these special accents with template tags such as the the_category() tag. Note: the_category() template tag lists, in post meta data section, the various categories assigned to a post.
In this example, the special character entity, the heart (♥) symbol, separates the categories of WordPress, Computers, and Internet News:
<?php the_category(' ♥ ') ?>
In this example you see the use of an accent in your post's title:
<?php the_title('∞ ', ' ∞'); ?>

<div id="author">♦ <?php the_author(); ?></div>
