Original GitHub issue: https://github.com/DavidAnson/markdownlint/issues/536

I had the following, and originally thought it was the accented characters, but it looks like it's actually the fact that Markdownlint keeps the ', but GitHub strips it in the auto-anchor

Remember that GitHub lower-cases every character when making the link for a heading. Your sample still has a capital letter (É) - lower-casing it passes the rule as currently implemented: https://dlaa.me/markdownlint/#%25m%23%20Issue%20536%0A%0A%23%23%20Donn%C3%A9es%20pour%20l'%C3%89change%20de%20ressources%20ouvert%0A%0A%5BFran%C3%A7ais%5D(%23donn%C3%A9es-pour-l%C3%A9change-de-ressources-ouvert)%0A

There are probably a few different ways this could work, but the all-lower-case the rule enforces now reflects what shows up in the browser URL (in Chrome) and seems like a reasonable canonical implementation.

Yeah, looks like I was missreading the double encoding characters as the apostrophe then the accent character, but it was just the accented character. I know this rule gets a little fuzzy since it isn't a CommonMark spec'd thing.
PS: also ran into an issue with the MDN content repo because their anchor generator behaves differently, but I haven't come up with an option proposal yet
