正则表达式允许所有国际字符但不允许符号

Question

我已经编写了以下允许所有国际字符（拉丁语、亚洲语……）的正则表达式

\n

 'D\xc3\xbcsseldorf, K\xc3\xb6ln, \xd0\x9c\xd0\xbe\xd1\x81\xd0\xba\xd0\xb2\xd0\xb0, \xe5\x8c\x97\xe4\xba\xac\xe5\xb8\x82, \xd8\xa5\xd8\xb3\xd8\xb1\xd8\xa7\xd8\xa6\xd9\x8a\xd9\x84 !@#$'.match(/[\\p{L}-]+/ug)\n

\n

但我想让它不允许所有特殊字符，例如!?})%....

仅包含字母、数字、破折号、点、逗号和空格的匹配字符串：

\n

\r\n

\r\n

console.log(\n  /^[\\p{L},.0-9\\s-]+$/u.test(\'D\xc3\xbcsseldorf, K\xc3\xb6ln, \xd0\x9c\xd0\xbe\xd1\x81\xd0\xba\xd0\xb2\xd0\xb0, \xe5\x8c\x97\xe4\xba\xac\xe5\xb8\x82, \xd8\xa5\xd8\xb3\xd8\xb1\xd8\xa7\xd8\xa6\xd9\x8a\xd9\x84 !@#$\')\n)\nconsole.log(\n  /^[\\p{L},.0-9\\s-]+$/u.test(\'D\xc3\xbcsseldorf, K\xc3\xb6ln, \xd0\x9c\xd0\xbe\xd1\x81\xd0\xba\xd0\xb2\xd0\xb0, \xe5\x8c\x97\xe4\xba\xac\xe5\xb8\x82, \xd8\xa5\xd8\xb3\xd8\xb1\xd8\xa7\xd8\xa6\xd9\x8a\xd9\x84\')\n)

\r\n

\r\n

\r\n

\n

结果：false和true。
