Regex for french characters fails validation based on the position of french character

Question

In my code I had a Password RegEx (written by someone) (/^(?=.*[a-z])(?=.*[A-Z])(?=.*\d)[\x20-\x7E]{8,40}$/) which was not supporting french characters. And I modified it a bit to support french characters. And /^(?=.*[a-z])(?=.*[A-Z])(?:.*[àâäæèéêëîïôœùûüÿçÀÂÄÈÉÊËÎÏÔŒÙÛÜŸÇ]*)(?=.*\d)[\x20-\x7E]{8,40}$/ is the new RegEx. But this one does not work as expected. The behavior changes with the position of the french character. For example, NewàTest123! - works and NewTàest123! does not works

Any thoughts on why it fails when the position of the character changes?

Add these chars to the ASCII matching character class, see https://regex101.com/r/HzACAw/1 — Wiktor Stribiżew, Jan 07 '19 at 13:25
That works. Thanks!! Any idea on why the other one that I posted was not working? — Faisal Khan, Jan 07 '19 at 13:33
