How can the browser be instructed to interpret a webpage as UTF-8 for correct umlaut display?

To ensure correct umlaut display on a webpage, the browser can be instructed to interpret the page as UTF-8 by setting the appropriate meta tag in the HTML head section. This meta tag specifies the character encoding to be used for the document, allowing the browser to correctly render special characters like umlauts.

<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
</head>
<body>
<!-- Your webpage content here -->
</body>
</html>
