JavaScript

 A string containing JavaScript which is passed to wp_add_inline_script()
 is sometimes rendered invalid when strings within it contain quotation
 marks. As an example:

 {{{#!php
 <?php
 wp_add_inline_script( 'jquery-ui-datepicker', '"Aujourd\'hui";' );
 }}}

 will output the following:

 {{{
 <script>
 "Aujourd"hui";
 </script>
 }}}

 Interestingly, reversing the quotation marks results in the same output:

 {{{#!php
 <?php
 wp_add_inline_script( 'jquery-ui-datepicker', "'Aujourd\"hui';" );
 }}}

 also gives:

 {{{
 <script>
 "Aujourd"hui";
 </script>
 }}}

 Either way, valid JavaScript is passed in, and invalid scripts are spit
 out. Anyone know what is going on?
