Rong alfabet

The Lepcha script, or Róng script, is an abugida used by the Lepcha people inhabit in Sikkim, India, to write the Lepcha language. Lepcha is derived from  The Tibetan script  0F40–0F6C in XVIII century. In present days, it is probably out of use. Originally, its manuscripts were written vertically, but later they were written horizontally. It should be noted that the characters weren't rotated through 90 degrees. Such a phenomena produced a whole set of final consonants.
