French is written with the 26 letters of the basic Latin script, with four diacritics appearing on vowels (circumflex accent, acute accent, grave accent, diaeresis) and the cedilla appearing in “ç”.
There are two ligatures, “œ” and “æ”, but they are now often not used because of the layout of the most commom keyboards used in French-speaking countries. Yet, they cannot be changed for “oe” and “ae” in formal and literary texts.
