Hello KCC2,
That's a great question! It's always good to know what formats we should be using when entering data in for our employees. I'm happy to explain how things work in QuickBooks Online and QuickBooks Online Payroll services.
While you can enter French accents into QuickBooks Online and its payroll services, this can cause problems when it comes to printing and processing things in the program and it has trouble reading and recognizing the symbols. This has shown to be particularly true for payroll. It's something that's been brought up to our engineering team so that we can smooth this over since we know accents often make a big difference in the French language.
While we're working on this, we recommend that you don't enter French accents into the program to ensure that everything runs properly.

I hope that helps! Please let me know if you have further questions.
