[Zope] Structured text and MySQL

Hello, I use MySQL to keep informations about my comics. In this DB, I've got a field with structured text in it. When I render it, it just render fine except when I use non-ascii caracters ie *foo* -> <em>foo</em> but *école* -> *école* Is there any work around ?? -- (°> Nicolas Évrard / ) Liège - Belgique ^^
