例如，如果有像ღ，❤等字符，有没有办法可以从python中的字符串中删除它们？我不想添加一个删除所有非英语字符的过滤器，因为可能还有其他有意义的语言。
答案 0 :(得分：0)
所有Unicode 10个人表情符号的正则表达式，不包括拉丁字符
如果您需要匹配系列，请执行以下操作：
01F468 MAN
01F3FB EMOJI MODIFIER FITZPATRICK TYPE-1-2
00200D ZERO WIDTH JOINER
002695 ⚕ STAFF OF AESCULAPIUS
00FE0F ️ VARIATION SELECTOR-16
使用正则表达式将单个表情符号与已知系列组合使用 适当的木匠和/或变体选择器。
