 post_class() function outputs category/tag specific classes using its slug
 (introduced at [8641]).

 But, allowed characters are different between slug and css class name.
 (css class name can use [-_a-zA-Z0-9] and non ascii unicod chars)
  A "%" character is allowed for slug, but not for css name.
 Therefore, invalid class name will be created.

 Eg: A user creates "携帯" category (Japanese word for "mobile"), the
 category slug will be "%e6%90%ba%e5%b8%af" and post_class() outputs
 'class="post hentry category-%e6%90%ba%e5%b8%af"'.
 This is an invalid class name.

 Avoid this situation, escaping "%" character with backslash "\":
 category-\%e6\%90\%ba\%e5\%b8\%af"
 This class name is valid. But this seems dirty.

 I suggest using class ID insted of class slug.
