检测*all*emojis

现在我正在使用这段代码:

public static bool ContainsEmoji(this string text)
{
    Regex rgx = new Regex(@"\p{Cs}");
    return rgx.IsMatch(text);
}

它有点帮助.

他们中的大多数似乎被发现,但有些则没有.

以下是帮助的参考列表:http://unicode.org/emoji/charts/full-emoji-list.html

所有的笑脸似乎都很好,但这些特定的表情符号并没有被正则表达式所抓住:

1920 U +2614☔雨伞下雨

1921年U +26F1⛱伞在地上

1922年U +26A1⚡高压

1923年U + 2744❄雪花

在键盘上这些并不是彼此靠近,但在列表中它们是相互跟随的,所以我只是假设有一个点它将开始不在表情符号列表中工作,并且它不是真正的验证.从1905年(天气般的表情符号),下降,一些被捕获在正则表达式,一些不是.似乎没有任何规则.

我不能只是去全ASCII,因为我需要人们输入像西里尔字母这样的字符,但我不能特别接受表情符号.我不知道如何从这里前进.

我阅读了关于代理高/低对的MSDN文档,但在这个阶段这对我来说非常混乱,我认为一些正确的方向推进将会有很长的路要走.

非常感谢您的宝贵时间 :)

您可以使用以下正则表达式匹配UTR#51(版本:11.0)文件的表情符号键盘/显示测试数据中定义的所有3518表情符号字符:
