arabic support

when we use with arabic content the excerpt of post show “?????” question mark, to solve this problem you need to change function in “class-instant-articles-post.php”
inside this file find function named “to_instant_article” inside this function find “htmlspecialchars_decode” and replace with “htmlspecialchars” then save the changes.
after that show the excerpt of post in arabic
