character à

Hi, i've installed wodrpressmu ( french version) and I want to insert the category "Lire à gauche". When I want to see the category, it was only saved as "Lire". In the database , wp_sitecategories, i have as cat_name "Lire" and category_nicename =lire-a-gauche. It seems a problem with the character "à". Could you help me with that ?
