用于捕捉表情符号的所有肤色变化的正则表达式

Question

I'm trying to use a regex to capture tweets containing the substring 👏 at least twice, so I'm using an unsophisticated ^.+ 👏 .+ 👏 .+$ . However this doesn't match strings which instead contain, for example, 👏🏼 .

Is there a smart way I can capture an emoji with any or none skin-tone variation, without just putting each one in a row (like [👏👏🏻👏🏼👏🏽👏🏾👏🏿] )?

Answer 1

Thanks to comments above, I've found that emojis I've encountered on twitter are unicode, and skin-tone variations are combining characters in the range 1f3fb – 1f3ff .

http://unicode.org/reports/tr51/#Emoji_Modifiers_Table

So for me what I wanted was 👏[\\x{1f3fb}-\\x{1f3ff}]? , with [\\x{1f3fb}-\\x{1f3ff}]? being something I can then drop next to any unmodified emoji to include skin-tone variations.
