character é in the database

Hi, Tanks for your response. I tried several things :

First : I copied my existing DB in a new DB for update
Second : Creating a new DB then copy my existing data in the new DB
Third : Export $ import

When i correct an accent from the application, he's encoded in latin1 in my DB like this : "testaccenté". Despite of my DB configuration :

character_set_client utf8
character_set_connection utf8
character_set_database utf8
character_set_filesystem binary
character_set_results utf8
character_set_server utf8
character_set_system utf8
character_sets_dir /usr/share/mysql/charsets/
collation_connection utf8_unicode_ci
collation_database utf8_general_ci
collation_server utf8_general_ci
