About

Nuosu SIL is a single Unicode font for the standardized Yi script used by a large ethnic group in southwestern China. Until this version, the font was called SIL Yi.

The traditional Yi scripts have been in use for centuries, and have a tremendous number of local variants. The script was standardized in the 1970’s by the Chinese government. In the process of standardization, 820 symbols from the traditional scripts of the Liangshan region were chosen to form a syllabary.

The syllable inventory of a speech variety from Xide County, Sichuan was used as the phonological basis for standardization. For the most part there is one symbol per phonologically-distinct syllable and vice-versa. The direction of writing and reading was standardized as left-to-right. Punctuation symbols were borrowed from Chinese, and a diacritic was incorporated into the system to mark one of the tones.

Character inventory

Nuosu SIL includes a complete set of Yi syllables and radicals as defined in the Unicode Standard, plus a basic set of Latin characters and punctuation. Yi radicals which were added to Unicode 3.2 (U+A4A2..U+A4A3, U+A4B4, U+A4C1, U+A4C5) are also included in the font. Representative samples:

Radicals

Requirements

Nuosu SIL is designed to work on systems and with applications that provide support for TrueType fonts and for Unicode character encoding. It does not include any smart font behavior.

Keyboarding

This font can be used with any preferred Yi Unicode keyboard. The SIL Yi keyboard is also available; however, it does not provide keystrokes for the Yi Radicals which were added to Unicode 3.2 (U+A4A2..U+A4A3, U+A4B4, U+A4C1, U+A4C5).
