Modifier Tone Letters
Modifier Tone Letters is a block of the Unicode standard that contains characters used to indicate tone in languages that use the Latin alphabet. In tonal languages, the pitch of a word can change its meaning, so it is important to represent this information accurately in writing. The characters in this block are used as diacritical marks, which are added to existing Latin letters to indicate the tone of a word. This block is often used in conjunction with other Unicode blocks to represent tonal languages in digital form.
