Umlauts on a webpage

Is there any problem with useing umlauts on a webpage ?.the umlaut characters are displaying good on the client side. But when i open the same document on the web. Then it creates a weird character combo like Á, instead of Ä and there are many more examples.

i have also tried enabeling the “Character set in header” and the “Meta character set” in the domino webserver setting.

Im using the text in a radiobutton field.

thnx in advance
