I noticed that in german languages, the open quotes are being rendered as a single quote mark like ,
when it should be rendered with two like ,,
I was able to test this by simply changing the font to roboto and the quotes were being rendered properly. This is in chrome and firefox.
sample with Poppins as Font family

same sample with Roboto as the font family

As you can see in the first example the open quote is not being rendered as it should based on german language standards.
