Hello, my name is Marco and I am an Independent Advisor. I will do my best to help you.
I have a French Canadian keyboard, and I press once on the '(the first next to the ENTER key) and then on the U, which makes ù or è or à or ò etc.
(But there are different keyboard designs, It can be the 2nd key. )
See the photo below.
If that doesn't work you have to set your keyboard layout to 'French (Canada)' everywhere.
In Windows settings > Time & Language > and set " Preferred language to " French ( Canada ) , then click on the language and select " option ".
Scroll down under " Keyboard " and choose " Canadian French " ... not " Canadian French legacy " .
And finally, make sure that in the task bar the FR Canadian language is selected.
