A fix could be to replace the programming apostrophe with the actual French apostrophe.
Use: ’
Not: '
This symbol does not exist on US QWERTY keyboards and does not exist either on older AZERTY ones but it does exist on both new AFNOR (Association française de normalisation) standard French keyboards, either new AZERTY or BÉPO.
It wouldn’t fix the deeper issue that the programmatic apostrophe is not correctly escaped, but the real French apostrophe is the correct one to use and should be the one most French speakers will use in typing once a majority of them will be on standard keyboards.
The old AZERTY was never actually standardized by any official body.
