Hello ! I just upgraded my blog from WP 1.02 to 1.2, and it seems it screwed something up. All the special french characters (accentuated a's and e's) in existing posts were replaced with chinese characters (or japanese kanjis, but that's not the point). Hell, even the blog title (RÃ´le de Je) is acting up. (Check it on http://www.gap-online.net )
The weirdest part is that the latest post, which I added after the upgrade, doesn't seem to be affected by this... and another surprise was to see that when trying to edit an older post, the kanji-whatever-thingy also appeared instead of the original text. Could it be the database was somehow affected by the upgrade ?
I tried to find similar problems in the archive, without success. I hope you can help... Guess I'll turn back to WP 1.0.2 in a week or so if there's no solution :p
