Table of Contents for this web page:
The Nuosu SIL Font 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.
The font includes a complete set of Yi syllables and radicals (as defined in The Unicode Standard,), a basic set of Roman glyphs and various punctuation. Yi Radicals which were added to Unicode 3.2 (U+A4A2..U+A4A3, U+A4B4, U+A4C1, U+A4C5) are now included in the font. Representative samples are below.
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.
You will need to use a keyboard program, but can use any Yi Unicode keyboard you prefer. We do provide a minimal Keyman keyboard which can be downloaded below. 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).
