U+1089 Myanmar Sign Shan Tone-5

The Wikipedia has the following information about this codepoint:

The Shan language is the native language of the Shan people and is mostly spoken in Shan State, Myanmar. It is also spoken in pockets in other parts of Myanmar, in Northern Thailand, in Yunnan, in Laos, in Cambodia, in Vietnam and decreasingly in Assam and Meghalaya. Shan is a member of the Tai–Kadai language family and is related to Thai. It has five tones, which do not correspond exactly to Thai tones, plus a sixth tone used for emphasis. The term Shan is also used for related Northwestern Tai languages, and it is called Tai Yai or Tai Long in other Tai languages. Standard Shan, which is also known as Tachileik Shan, is based on the dialect of the city of Tachileik.

The number of Shan speakers is not known in part because the Shan population is unknown. Estimates of Shan people range from four million to 30 million, with about half speaking the Shan language. Ethnologue estimates that there are 4.6 million Shan speakers in Myanmar; the Mahidol University Institute for Language and Culture gave the number of Shan speakers in Thailand as 95,000 in 2006, though including refugees from Burma they now total about one million. Many Shan speak local dialects as well as the language of their trading partners.
