ClassNotFoundException: Attempted to load class "Utf8"

[xchs]

I get the following error message when I try to include the front end module in the article:

ErrorException: Uncaught Symfony\Component\Debug\Exception\ClassNotFoundException: Attempted to load class "Utf8" from namespace "InspiredMinds\ContaoSiblingNavigation\Module".
Did you forget a "use" statement for "Patchwork\Utf8"? in /vendor/inspiredminds/contao-sibling-navigation/src/Module/SiblingNavigationEvents.php:44

To reproduce:

• Create e.g. a new Event sibling navigation front end module
• Insert the module in the article

[Contao 4.6.6]
