Combining Diacritical Marks

● A diacritical mark is a "glyph" added to a letter.

● Some diacritical marks, like grave ( ̀) and acute ( ́) are called accents.

● Diacritical marks can appear both above and below a letter, inside a letter, and between two letters.

● Diacritical marks can be used in combination with alphanumeric characters to produce a character that is not present in the character set (encoding) used on the page.
