This is really weird.
Look at this screenshot.
In the parts I circled in red, words have some letters replaced by random ones (even if you don’t speak french it should be noticeable), but I can still guess the meaning.
Now look at this one. I zoomed on the text (220%) and the circled part became even more corrupted, to the point it’s almost unreadable.
Finally, I zoom out a bit to 180% and this is what I get. The green title is now looking normal, but one letter (circled in red), which previously appeared fine, changed. The below part is still looking weird though. It looks exactly like that when I zoom in to 250%.
I precise that this is originally an odt file, not a docx I converted in odt or something.
What in the hell is happening ?
