RegEx扩展拉丁字母（äöüèß） [英] RegEx with extended latin alphabet (ä ö ü è ß)

问题描述

我想在Node.js中做一些基本的字符串测试。假设我有一个表单，用户输入他们的名字，我想检查它是垃圾还是真名。

I want to do some basic String testing in Node.js. Assume I have a form where users enter their name and I wanna check if it's just rubbish or a real name.

幸福（或者我的支票很遗憾）我从中获取用户在世界各地，这意味着他们的名字包含非英文字符，如äöüßé。我习惯使用 / [A-Za-z - ] {2，} / ，但这与JanBuschtöns之类的名称不匹配。

Happily (or sadly for my check) I get users from all around the world which means that their names contain non-english characters, like ä ö ü ß é. I was used to use /[A-Za-z -]{2,}/ but this doesn't match names like "Jan Buschtöns".

我是否必须手动将每个可能的非英语但拉丁字符添加到我的RegEx才能工作？我不想要一个100多个字符长的RegEx，如 / [A-Za-z-äöüÄÖÜßéÉèÈêÊ...] {2，} / 。

Do I have to manually add every possible non-english but latin character to my RegEx to work? I don't want a 100+ characters long RegEx like /[A-Za-z -äöüÄÖÜßéÉèÈêÊ...]{2,}/.

推荐答案

检查 http：/ /www.regular-expressions.info/unicode.html 和 http://xregexp.com/plugins/

如果你想要，你需要使用 \p {L} 来匹配任何字母字符包含unicode。

You would need to use \p{L} to match any letter character if you want to include unicode.

说到unicode，替代 \w 是 [\ p {L} \p {N} _] 然后。

Speaking unicode, alternative of \w is [\p{L}\p{N}_] then.
