There seems to be a problem with the euro sign in gnumeric. I couldn't find a font that made gnumerice display the euro sign (and not show the "currency" sign). This is not true for the menus: if I insert the euro symbol in a cell, the currecy symbol is shown. However, the undo line in the edit menu now shows the euro symbol correctly. LANG=de_AT@euro
