I am surprised at the prominence of ™, ® and ©. Are they commonly used when typing in french, or is this likely an issue with the sources they used? e.g. source code with copyright notices, etc.

Theres also (to my mind) some oddities around the inconsistencies around é and É, and ù and Ù where they use different modifier keys to choose the upper and lower case variations.

Tilde ~ was removed? Ezh ʒ was added?

No doubt its better now you actually have the keys you need available for the language itself - but maybe it needed a bit of curation as to their selection and consistent modifier-key selection?

No it doesn't, it has the same uses than in english and therefore the same frequency of uses.

~ is available through altgr + n (as in ñ). Easy to remember in fact
