After upgrade, all French and Japanese characters don’t show anymore.

Hey guys,

it’s been a long since I had any problem with WordPress, except for the Podpress plugin issues but I already found a solution to this.

Today, I’ve upgraded one of my blog with the new 2.8.6 version of WordPress. Everything went well and I was able to upgrade without a single problem. Once on the dashboard, I decided to take a look at my blog and I was really upset when I noticed that every French word with an accent now shows weird symbols.

Pourtant au-del? de ce succ?¨s populaire, le v??ritable probl?¨me dans le paysage cin??matographique japonais, c’est la r??cup??ration politique du gouvernement et l’engouement d??plac?? de la plupart des m??dias japonais.

See? The funny thing is… if I write a new post, everything is working like a charm. All my previous posts however are doomed by this problem, as well as the title of my blog, a Japanese word.

Since I use three languages on this blog, French, Japanese and sometimes English, I really need it to show the characters as they should be showed…

Any idea? Thanks!
