Meet the diacritical marks

A combining mark attaches to a neighboring character. It can sit above or below a letter, and several marks can occur together.

One appearance, different encodings

é can be written as U+00E9, or as e (U+0065) followed by COMBINING ACUTE ACCENT (U+0301). These forms are canonically equivalent. Unicode normalization can convert between composed and decomposed forms.

A spacing accent symbol is not the same character as a combining mark. The dotted circle in Unicode charts shows where a mark sits; it is not part of the mark itself.
