Hello,
I'm running the latest WP version (2.8.4 actually) on my website, along with a vBulletin board that i run for years now.
vBulletin uses ISO-8859-1 and since i needed to have WP & vBulletin working together, i had to switch WP charset to ISO-8859-1.
(I've got ~140K posts on my boards so i decided to change WP charset instead of having to convert the boards to UTF-8.)
To end this quick sum up of the situation, EVERYTHING went OK and my WP installation is working in ISO-8859-1 (well... almost everything.)
I've got some charset conversion issues in the dashboard display, as you can see in this screenshot :

I suppose it's because of the AJAX features (jQuery ?) that loads the several dashboard widgets. When it comes to load some bits of my ISO translation, something goes wrong.
I also suppose that i've got to alter some parts of WP code to encode/decode the AJAX output.
Question is : where to perform theses modifications ?
Thx for your help :)
