“去掉组合附加符”去掉哪些？What does Strip combining marks remove?
先分解（NFD），只去掉附在拉丁、希腊、西里尔字母上的非间距附加符（Mn，如 é 的重音、ệ 的两个符号），再按所选形式重新组合，所以预组合和分解输入结果相同，任何规范化形式下都有效。不会去掉 Mc 间距符号、印地语等文字的元音符号和半音符、Emoji 变体选择符（FE00–FE0F、E0100–E01EF）、零宽连接符、键帽 U+20E3 和肤色修饰符。The text is decomposed (NFD) first, then only non-spacing marks (Mn) on Latin, Greek and Cyrillic letters are removed, such as the accent on é or the two marks on ệ, and the result is recomposed in the chosen form. So precomposed and decomposed input give the same result, with any normalization form. Spacing marks (Mc), Indic vowel signs and viramas, emoji variation selectors (FE00–FE0F, E0100–E01EF), zero-width joiners, the keycap U+20E3 and skin-tone modifiers are never removed.
