The Sundanese block contains characters used in the Sundanese script, which is used for writing the Sundanese language spoken on the island of Java, Indonesia. The script is an abugida, with each consonant having an inherent vowel that can be modified with diacritics. The Sundanese script was used in pre-colonial times for various texts, including literature, legal documents, and religious texts. Although it was largely replaced by the Latin alphabet during the colonial period, there has been a revival of the script in recent years as a symbol of Sundanese cultural identity..
