Merge pull request #37 from hkdobrev/htmlspecialshars-utf8

Prior to PHP 5.4.0 the default encoding for `htmlentities()`
and `htmlspecialchars` is "ISO-8859-1". For PHP 5.4+ is "UTF-8".

This ensures always the right encoding is used no matter the PHP version
and the locale settings.

-## Parsedown PHP
+## Parsedown
 
-Parsedown is a parser for Markdown. It parses Markdown text the way people do. First, it divides texts into blocks. Then it looks at how these blocks start and how they relate to each other. Finally, it looks for special characters to identify inline elements. As a result, Parsedown is (super) fast, consistent and clean.
+Fast, consistent and easy to use [Markdown][1] parser for PHP.
