Problem with GTK_LABEL in GTK2

[Johannes Böhler <johannesb surfeu at>]

Hallo,

I have problems with LABELS in GTK2. When I use ä, ö, ü in the
text-string, then I get a runtime-error.

the code:

label=gtk_label_new(NULL);
gtk_label_set_markup (GTK_LABEL (label), "<b>Böhler</b>");
gtk_widget_show(label);
gtk_box_pack_start (GTK_BOX (leiste), label, FALSE, FALSE, 0);

the error message:

app (pid:1652): Gtk-WARNING **: Failed to set label from markup
due to error parsing markup: Error on line 3 char 9:
Invalid UTF-8 encoded text

How do I use ä, ö, ü in GTK_LABEL?

Thank you.


Johannes
