How do you type an umlaut above a dash?

To type an umlaut above a dash, you typically need to use a combination of characters since there isn’t a standard character for that specific combination. You can use a special character for the umlaut (¨) followed by the dash (-), but it may not render as intended in all contexts. Alternatively, in graphic design or Word processing software, you can create the effect by layering text or using a text box to position the umlaut over the dash.
