How to avoid german Umlaut in Fckeditor??? PLEASE HELP!

Hi All
Am developing an application using the FCKEditor. My users may enter/edit some text in the editor window and save it to the database.
But everytime, FCKEditor transforms all the special german character (Umlaut) into something like &umll; for "ü".... My text is useless with this content.
I've tried different encoding (ISO-8859-1, CP1252, etc...) ... All them failed to solve my problem.
Could somebody help me solve this issue?
Thanks in advance
