West A., Zhamsoev A., Zaytsev V. [Document No.] JTC1/SC2/WG2 N4781 = L2/17-007: Proposal to encode one historical Mongolian letter for Buryat Mongolian // The Unicode Consortium: [official website]. 2017. 12 pp.
This is a proposal to encode in ISO/IEC 10646 and Unicode an additional Mongolian letter that was historically used for writing texts in Traditional Mongolian script by the Buryats of the Barguzin Steppe Duma in Russia. This letter is no longer used, but is required for encoding because scholars studying documents written in Traditional Mongolian script from Barguzin wish to be able to represent text using this letter in Unicode Mongolian.
