Try the Canadian Multilingual French layout on a standard QWERTY keyboard.

à is \

è is '

é is /

ç is ]

accent grave is right-alt+[+letter

and

"specials" are right-alt+num (±@£¢¤¬{}[]) but for any glyph used in programming, I usually switch back to US keyboard using alt+caps-lock. Ça fonctionne très bien pour moi!

On a ISO layout (with the inverted-L "enter" key), you also get ù between left shift and z.

Accolades ({}) and brackets ([]) are on alt-7-8 and alt-9-0. A bit annoying to type, but manageable. At least it's somewhat logical (pairs are next to one another).

What's nice is that this is the default French layout for Apple computers in Canada, so you can order one with the correct keys printed on it: https://www.apple.com/ca/shop/product/MK2C3LL/A/magic-keyboa...

Unfortunately this layout seems mostly unavailable with PC keyboards (I only seen a Lenovo model).

The CSA layout is pretty nice, I use it everywhere (writing French and writing code) and don't have problems with {}[]() because these characters are juxtaposed (unlike the french AZERTY).
