[英]How to make a generic regex expression to validate UTF-8 special characters in input through JS?
function myFunction() {
var str = "W";
var patt1 = /\u0057/g;
var result = str.match(patt1);
document.getElementById("demo").innerHTML = result;
}该函数将搜索W字符，因为\\ u0057是W的十六进制代码。
如果我尝试用var patt1 = / \\ u00 [（\\ w +）] [（\\ w +）] / g /来概括它； 此正则表达式无法正常工作。 为什么？
