If you have your blog hosted with acswebservices and recently had your site shifted to our new server you might find some odd characters showing up - it does depend on what version of Wordpress you are using.  The characters I mean show up like this: Week’s

This has something to do with a clash between the newer software on the server and that version of Wordpress.  But there is a fix.  You can download the wp-utf8-sanitize plugin which I’ve found to be very useful.  It’s worked about 95% of the time for these strange character sets that show up.  Just download the plugin, unzip the file, copy it to your plugins folder in your blog and then activate it in the plugins section in your Wordpress dashboard.
