EDIT The Limbu script is also known as Kiranti and Sirijunga. It is a Brahmic script and probably descendant of the Lepcha script, which is dissimilar to any other Indic script and probably derived from the Tibetan script.

Limbu is an abugida, which means that in this script every consonant has an inherent vowel that is always there unless the consonant gets modified with a vowel sign. The script has no seperate vowel characters, to be able to represent a vowel without a consonant, the vowel signs get attached to a vowel-carrier-letter (U+1900).

The codepoints U+1900-U+191C are consonants, U+1920-U+1928 are dependent vowel signs.
 
EDIT History The Limbu script was, according to local history, first created by the King Sirijonga Hang in the late 9th century, then fell out of use again for almost 800 years. It was brought into practise again by Te-Ongsi Sirijonga Thebe who was killed for that in 1741. Limbu was named »Sirijonga« in 1925 by the Iman Singh Chemjong to honour Te-Ongsi Sirijonga Thebe. Since Te-Ongsi\'s death, it was often difficult to use the Limbu script because, as an expression of cultural identity, it was taken as a threat against the unity of the country by the ruling social elites. At times, the use of the Limbu script and even the posession of texts written in Limbu was forbidden.
 
EDIT Language The Limbu script is used to write the Limbu language, spoken by the Limbu people of northeast Nepal and northern India. It is one of the major languages in Nepal. Common Limbu is known as Tajengpan, the priestly high language as as Mundumban. Limbu has four main dialects: Panchthare (the dominant dialect), Tamarkhole, Phedape and Chatthare. In 1991, only 1% of the people speaking Limbu could actually write in the Sirijangga script (40% could write in Devanagari).
 
EDIT Fonts Glyphs for the Limbu script are part of James Kass\' Font »Code 2000«. There is also a font from XenoType Technologies.
