We had an issue where RSS feeds showed funky characters when used to populate 'recent posts' listings on sister sites.

I found a couple of solutions involving disabling wptexturize, either by:

• editing /wp-includes/formatting.php to comment out the //add_filter('the_title', 'wptexturize'); calls
• editing a theme's function.php file
• adding a plugin like Disable wptexturize to disable the wptexturize filter.

I like the elegance of the Plugin method, as it is very concise (& doesn't require modifying CORE functions... ;-). However, I'd prefer that only RSS feeds be excluded from the wptexturize() functionality (I like curly quotes everywhere else).

Any ideas on how I might fix this so RSS feeds don't get wptexturize()'d, but everything else does?

NOTE: Modifying the Encoding for pages and feeds setting on 'Settings > Reading' helps, but only if the web page on which the RSS feed will be displayed matches the encoding specified.
