Javascript 使用正则表达式检测表情符号是否为国旗

我一直在尝试制作一个正则表达式，可以检测表情符号是否是国旗。我希望正则表达式匹配中的所有国旗。国旗表情对应于一对本地符号，两个字母标识国家，例如法国的FR-。 您可以使用与这些字母的任意组合相匹配的正则表达式。当然，这将包括不存在的国家代码，例如ZZ，但这应该排除任何其他表情符号

这就是：

var reg = /[\uD83C][\uDDE6-\uDDFF][\uD83C][\uDDE6-\uDDFF]/;
reg.test("Since the flags are essentially created from two Unicode characters, a possible option would be 
str.match(/[To keep the regex precise you can only build regex ranges.
