Yi script
Nasu (Naisu, Eastern Yi), or Nasu proper, is a Loloish language spoken by a quarter million Yi people of China. Nasu proper and Wusa Nasu are two of six Yi languages recognized by the government of China. Unlike most written Yi languages, Nasu proper uses the Pollard (Miao) script. A distinct form of the Yi script was traditionally used for Wusa, though few can still read it.
