U+012B "ī" Latin Small Letter I with Macron Unicode Character
Unicode Version 17.0
ī
U+012B "ī" Latin Small Letter I with Macron is a standardized character used in digital text to represent the letter 'i' with a horizontal line, or macron, placed above it. This diacritical mark indicates a long vowel sound in languages such as Latvian, Māori, Hawaiian, and standard romanizations of Japanese, Chinese, and Sanskrit. It is distinct from a simple 'i' combined with a combining macron, as U+012B is a precomposed form, ensuring consistent display and processing across different software and platforms without relying on character combination.
