Encoding of e-mail text is wrong

[LiaraAlis]

PHP Version

8.3.13

Shopware Version

6.6.10.5

Plugin Version

3.5.1

Actual behaviour

The logged email text does not appear to support Asian characters.

This:
Mit freundlichen Grüßen / 늘 건강하시고 행복하시길 빕니다
becomes
Mit freundlichen Grüßen / 늘 ê±´ê°•í•˜ì‹œê³ í–‰ë³µí•˜ì‹œê¸¸ 빕니다
in logged mails.

Expected behaviour

Logged text should be Mit freundlichen Grüßen / 늘 건강하시고 행복하시길 빕니다

Steps to Reproduce?

Create mail footer template with this line:
Mit freundlichen Grüßen / 늘 건강하시고 행복하시길 빕니다

Additional note: It should be a problem with the preview. Everything is fine in the downloadable .eml file.
