If you have issues with your blog with strange characters appearing due to a MySQL database Character Set not being UTF8 in combination with Wordpress, then this might be the solution for you:

bbwp2utf8 will attempt to convert a wordpress or wordpress mu database with content in whatever character set to utf8. It uses the information provided by this guide on the wordpress codex site.

This solves the issue with weird characters due to UTF8 encoding issues as seen in the screenshot below.

Development for this plugin is made possible by VPRO Digitaal and started after encountering numerous solutions including other plugins and none providing a 100% workable solution. If you need any help with this plugin, do not hesistate to contact me. My company is available for hire

Note: Keep in mind that this plugin has been tested thoroughly for wordpress mu, but only minimaly for wordpress. Please contact me if you encounter any issues with Wordpress, patches are always welcome.

Visit this link http://wordpress.org/extend/plugins/bbwp2utf8/ to download the plugin or to get more detailed info.

Make sure to have a working backup of your wordpress (mu) database before using this plugin!
