Tibetan

"Tibetan is one of the oldest Sino-Tibetan language to be recorded. The earliest Tibetan inscriptions date from 7th to 8th century CE in what is called the dbu can (which translates into "with a head") script, which also appeared on manuscripts from around 11th CE and remained until the modern day in the form of printed Tibetan text. Another script tradition, the dbu med ("without a head", "acephalous"), appearing first around the 12th century CE. The main difference between the two script traditions is that the dbu can script has the top line (hence the name "with a head") and less cursive than the dbu med script."
