French words with accent are not properly saved

Hello,

I have tried sending an email to support at Voki several times and received one response which wasn't helpful, I teach in a French school and my students are trying to type their text in Voki. Once they save it, any French word with an accent turns into a weird symbol and the avatar can't read it. I have used Voki for the last several years and have never had this problem. When the support person emailed me back he said most words in French don`t have an accent and to ignore those words. Worst. Advice. Ever! Almost every word in French has an accent. We need to evaluate this project and have been waiting almost 2 weeks for help. I have sent the letters with the accents I need added twice and no reply.

Please help!
