How can PHPStorm be configured to automatically replace Umlauts with HTML entities like ä?

To automatically replace Umlauts with HTML entities like ä in PHPStorm, you can use a custom Live Template. This will allow you to type a shortcut and have it expand into the desired HTML entity.

1. Go to PHPStorm Preferences -> Editor -> Live Templates
2. Click the "+" button to add a new template
3. Enter a abbreviation (e.g. "umlaut") and a description
4. In the template text field, enter the HTML entity (e.g. "ä")
5. Set the context to "HTML" or "PHP" to limit where the abbreviation can be expanded
6. Click "Apply" and then use your abbreviation in your code to automatically replace Umlauts with HTML entities
