U+0101 "ā" Latin Small Letter A with Macron Unicode Character

U+0101 "ā" Latin Small Letter A with Macron is a precomposed letter used primarily in the Latin script for languages such as Māori, Hawaiian, Latvian, and romanized Mandarin Chinese (Pinyin), where it represents a long vowel sound or a specific tonal variant. Its glyph consists of a standard lowercase 'a' topped with a horizontal bar called a macron, distinguishing it orthographically from the plain 'a' to indicate a difference in pronunciation or meaning. In digital text, this character is encoded as a single code point rather than a base letter followed by a combining macron, ensuring consistent rendering and compatibility across Unicode-compliant systems.
