如复制文字到Anki输入框，发现这“足”和“而”明显跟正常的汉字长得不一样：
其实它不是正常的汉字“足”和“而”，而是康熙部首，这些文字在非汉字字体如常见的Consolas、Courier New、Courier是不会被正确渲染，而是直接显示成框框的，因为他们是在汉字的[\u4E00-\u9FFF]编码区外的字符，只是长得像汉字的“足”和“而”，而非正常的汉字。大部分可以用"NFKD"或"NFKC"规范化形式校正过来，但也有少量字符不会进行规范化：
这一部分可以校正过来：

如Python中可以完美解决：
但这一部分无法校正过来
<|"⼞" -> "口", "⾒" -> "儿", "⾞" -> "车", "⾤" -> "采", "⾧" -> "长",
"⾨" -> "门", "⾭" -> "青", "⾴" -> "页", "⾵" -> "风", "⾶" -> "飞",
"⾺" -> "马", "⿂" -> "鱼", "⿃" -> "鸟", "⿄" -> "卤", "⿒" -> "齿",
"⿓" -> "龙"|>
但也不要紧，除了“⼞”需要额外手动添加到校正列表，其它的都算解决了。可以注意到只有“长得”完全一样的情况下"NFKD"或"NFKC"规范化才会进行，这可以帮我们解决绝大部分问题。不过我注意到除了康熙部首，还有部分补充偏旁是无法通过"NFKD"或"NFKC"规范化来进行修正的，这一部分只能用简单的字符串替换来修正，我挑了些汉字而非偏旁来作汉字替换列表如下：
<|"⼞" -> "口", "⺒" -> "巳", "⺎" -> "兀", "⺏" -> "尣", "⺓" -> "幺",
"⺔" -> "彑", "⺛" -> "旡", "⺝" -> "月", "⺞" -> "歺", "⺟" -> "母",
"⺠" -> "民", "⺢" -> "氺", "⺩" -> "王", "⺬" -> "示", "⺯" -> "糹",
"⺽" -> "臼", "⺾" -> "艹", "⻁" -> "虎", "⻃" -> "覀", "⻄" -> "西",
"⻆" -> "角", "⻈" -> "讠", "⻋" -> "车", "⻑" -> "長", "⻒" -> "镸",
"⻖" -> "阝", "⻘" -> "青", "⻙" -> "韦", "⻚" -> "页", "⻛" -> "风",
"⻜" -> "飞", "⻝" -> "食", "⻢" -> "马", "⻣" -> "骨", "⻤" -> "鬼",
"⻥" -> "鱼", "⻦" -> "鸟", "⻧" -> "卤", "⻩" -> "黄", "⻪" -> "黾",
"⻫" -> "斉", "⻬" -> "齐", "⻭" -> "歯", "⻮" -> "齿", "⻯" -> "竜",
"⻰" -> "龙", "⻱" -> "龜", "⻲" -> "亀", "⻳" -> "龟"|>
现在根据"NFKC"和最后面这个手动替换列表制作.exe文件在附件（代码托管在github中），让它在后台运行，它会自动纠正剪贴板中汉字的编码问题。另外，我这么用后台.exe来处理的方式只是权宜之际，麻烦官方尽快修复这问题，拜托了，如果技术上需要斟酌可以再联系我…MarginNote assistant.exe (44.0 MB)
