There are several diactric marks that alter the vowel sound of a letter. Two diacritics are used exclusively for Pali and are rarely seen elsewhere.
One or more of these accents can be added to a consonant to change its sound. In addition, other modifying symbols are used to differentiate tone and sound, but are not considered diacritics.
