According to Michael Everson's site, "The Alphabets of Europe" page, the French .pdf, character � and � (Latin small / capital letter N with tilde) is used by the French alphabet.
The reason it is in that list is because there are some loanwords in French which retain the letter. Ca�on is one of these.
