Namdhinggo SIL L Font (Endorsed)

Current version: 1.001, released June 16, 2007

According to traditional histories the Limbu script was developed by King Sirijonga in the 9th Century. It then fell out of use before being reintroduced in the 18th century by Teongsi Sirijonga (1704-1741) whom many felt to be the reincarnation of the first Sirijonga. The modern Sirijonga was apparently martyred in 1741 for the sake of this script by lamas in Sikkim. The script was named 'Sirijonga' in his honour by the Limbu scholar Iman Singh Chemjong.

The current font-Namdhinggo SIL L-uses an encoding that is common among other fonts for the script. Although the Limbu script has been accepted into The Unicode Standard, this font does not yet support that international standard. A Unicode-based version of Namdhinggo SIL is currently in the final stages of development.
