Accents not processed correctly on some feeds

Hi, for the past couple months, I have several feeds where accents (I’m french speaking) are not displayed correctly. It used to work fine before, and still works in other RSS aggregators that I tried. So it seems a problem on Newsblur side.

Here is one example : https://www.journaldugeek.com/category/science/feed/

Can you have a look?

Thanks!!!
