ISO 15924 script code: Mong

The Mongolian script, originally derived from the Old Uyghur alphabet, is the traditional writing system of Mongolia and is used primarily for the Mongolian language. It's unique for its vertical alignment, unlike most scripts which run horizontally. While the script is dominant in Inner Mongolia, China, it's less common in Mongolia due to Cyrillic script's prevalence. Modern operating systems support it, though fonts and input methods can vary.
