Indeed, a principal difference of these alphabets is the remapping of French vowels with a grave accent (à è ì ò ù) to an acute accent (á é í ó ú), as the French alphabet does not support acute accents apart from é. Spanish changes all five of these vowels, as well as taking ü. Portuguese Braille is also very similar to the French, though the shift of grave to acute accents necessitated a chain of other changes, such as circumflex to grave, and the Portuguese tildes were taken from French diaereses (Portuguese ã õ for French ä ö/œ).

The continental Scandinavian languages took the extended French letters â (for å), ä/æ, and ö/ø.
