I want to set a text in a label:

labelDemnaechst.setText(" Demnächst fällig:");

On the output in the application the characters "ä" are displayed wrong.

How can I display them well?

GWT assumes all source files are encoded in UTF-8 (and this is why you see löschen if you open them with an editor that interprets them as Windows-1252 or ISO-8859-1).

GWT also generates UTF-8-encoded files, so your web server should serve them as UTF-8 (or don't specify an encoding at all, to let browsers "sniff" it) and your HTML host page should be served in UTF-8 too (best is to put a <meta charset=utf-8> at the beginning of your <head>).

If a \u00E4 in Java is displayed correctly in the browser, then you're probably in the first case, where your source files are not encoded in UTF-8.
