French accents are not matching accents from common keyboard layout

For example the word "siècle" 0x736965cc80636c65 will not match the word "siècle" 0x7369c3a8636c65.

One is coming from the word list and the other from utf8 text from any website.

I do not know which is the "correct" solution:

Either both are good and should match the typed word.
Only one is good and must respect the specification.
Maybe it's more subtle and shall match depending on the dialect, for example maybe those might be accents from canadian keyboard layout, etc...

I'll probably find a workaround of my own to input this correctly. This might be worth looking into.
