Accents not processed correctly on some feeds

I forgot to mention, I use the TEXT view to get the full content.

I’m using Newsblur web with Edge v144.0.3719.92 on W11 at work. That’s where I have the problem. All extensions are disabled. (On Mac and iOS I use 3rd party apps that don’t show the issue)

Here is what I see using the TEXT view :

The posts before November 21st 17:02 don’t have the issue, all posts since then look like the screenshot with no accents inside the text (title is fine).

Tried with Firefox, same issue but seems more random, some news have accents, others don’t.
