Saving accents and umlauts using midas

Hi

I'm incorporating the midas editing component of mozilla in our CMS tool.
The problem I'm having is that when I save a page containing letters 
with accents or umlauts (I work for a German company) using JavaScript, 
it seems as if the page is being saved with the wrong encoding.
Anyone an idea on how I can specify that these characters should be 
saved "as is" ?

After the content is grabbed with .innerHTML it is passed to a 
java-servlet, which saves the actual page.
