I know this is a FAQ for the general WordPress community, and has come up for WPMU before, but in the last upgrade the texturize code appears to have moved again, and I'm trying to figure out where it is. Previously I could just comment out specific lines for specific substitutions (for quotes, ellipses, etc.).
I mostly want these characters eliminated from the RSS feed, but am willing to kill them off sitewide if that's simpler. I see some code (referring to cockney?) in /wp-includes/formatting.php, but unlike the previous setup it's not as easy to stop specific substitutions.
Any suggestions? Or do any of the WordPress plugins for this work site-wide for WMPU?
