Positional Mismatches in Mongolian Encoding | 蒙系文字编码中的位置失配 Author | 作者: SHEN Yilei | 沈逸磊(shenyileirob@) L2/17-332 WG2 N4884 Date | 日期: 2017-09-21 [The author would like to thank LIANG Hai (梁海), MA Xudong (马旭东), WANG Yihua (王奕桦), YAN Shi (嚴實), and ZHENG Weizhe (郑维喆), among others, for their insightful discussion into this issue.] 【感谢梁海、马旭东、王奕桦、严实、郑维喆等诸君对此问题的深入讨论。】 This document discusses the problems of positional mismatches that exibit in the current Mongolian encoding of the Unicode Standard. It is argued that these mismatches should be rectified at a later point, and a full list of mismatches is given. 本文讨论现行 Unicode 标准中蒙系文字编码中的位置失配问题，提议今后时机适当时应当修正这些失配，并 给出了失配全表。 0 Preliminary notes | 预备性说明 Owing to the pervasive editorial errors in the transfer of the variant specification from StandardizedVariants.html (henceforth SV.html) to the code charts since Unicode 7.0, the Mongolian variant specification in the present discussion is based on SV.html, the Mongolian section of which has remained unchanged from beginning (Unicode 3.2) to end (Unicode 8.0). We shall not blame the editors as SV.html did not overtly list no-FVS forms, and when attempting to recover these forms in the code charts, errors are almost inevitably made on whether there is a no-FVS form and what it is. In view of this, I have resorted to TR170, the document most conforming to SV.html yet having a full specification of the variants, for the no-FVS forms. A full chart of the Mongolian variant specifications in TUS without editorial errors is given in Appendix A. 7.0 版以降的 Unicode 标准将变体的规定从 StandardizedVariants.html （以下简称 SV.html ）转移到了码表中， 可惜这个过程充斥了大量的编辑错误。故本文讨论的蒙系文字变体规定一以 SV.html 为准，因为 SV.html 关 于蒙系文字的规定从头（Unicode 3.2 ）到尾（Unicode
