je dois utiliser les fonctions utf8_encode() et utf8_decode() dans la page du plugin , car dans les pages du portail ,d'autre plugins envois des infos dans la base comme celui ci est ça marche

dans ma page j ai trouvé ça et je l ai mi en place .
et ça plante

string utf8_decode ( string $row )

mais information sont dans quel variables

$inputstr
$fieldname
$fieldtype
$row

L'UTF-8 gère les accents normalement. Essaye plutôt <META HTTP-EQUIV="Content-Type" CONTENT="text/html;charset=iso-8859-1"> pour les écritures européennes et iso-8859-15 pour gérer le iso-8859-1 + le signe euro.
