Hello Karen,
Perhaps you could try installing the Microsoft PowerToys application, which has a Quick Accent feature. This is is an alternative way to type accented characters, useful for when a keyboard doesn't support that specific accent with a quick key combo. This tool is based on Damien Leroy's PowerAccent.
This utility is turned off by default. In order to use the Quick Accent utility, you will need to open PowerToys Settings, select the Quick Accent utility tab, and set the Enable toggle to "On". You can refer to the following link for specific information.

And the Microsoft PowerToys application has many other features, you can refer to the following article for more information.

I hope the above information will be helpful to you. Feel free to post back if you need further assistance.
