The package provides the Soyombo script and the Soyombo symbol for LaTeX users. The script and the symbol were both developed in 1686 by the Mongolian monk and scholar Zanabazar. Soyombo script is modelled after Lantsa-Devanagari, and it combines the phonemic repertoire of Mongolian, Sanskrit, and Tibetan.

While the script is now little used, the symbol appears very widely (including the national flag).
