All Unicode-enabled Regex flavours should have a special character class like \w that match any Unicode letter. Take a look at <a href="http://www.regular-expressions.info" rel="nofollow noreferrer">your specific flavour here</a>.

You do the same way as any other character matching, but you use \uXXXX where XXXX is the unicode number of the character.

The situation with regexes, Unicode, and Javascript sucks. It's ridiculous that programmers should have to rely on external libraries to recognize that "Αλφα" is a word, or even that "é" is a letter.

But so it goes. 

This guy has written a good library for handling Unicode in Javascript Regexes:

<a href="http://blog.stevenlevithan.com/archives/javascript-regex-and-unicode" rel="noreferrer">http://blog.stevenlevithan.com/archives/javascript-regex-and-unicode</a>

The Unicode stuff is a plugin to this regex library:

<a href="http://xregexp.com/" rel="noreferrer">http://xregexp.com/</a>

Here's a post about the Unicode extension:

<a href="http://blog.stevenlevithan.com/archives/xregexp-unicode-plugin" rel="noreferrer">http://blog.stevenlevithan.com/archives/xregexp-unicode-plugin</a>

And the extension page itself:

<a href="http://xregexp.com/plugins/" rel="noreferrer">http://xregexp.com/plugins/</a>

Great work but it still bums me out that Javascript is so backwards in this regard.

(He wrote a book for O'Reilly about the topic so it's quite possible that he knows what he's talking about.)

The way he implemented it is by adding tables of characters with certain properties. Then, when you contruct a regex with his library, <code>\p{charclass}</code> gets replaced with <code>[allthecharactersintheclass]</code>.

blocks|key|1736017|text|Jeremy+Ruten给出的答案很棒，但我认为这并不是Paul+Wicks所寻找的。如果我没理解错的话，保罗问我关于表达式，以匹配非英语单词，如können或móc。Jeremy的正则表达式只匹配非英语字母，所以需要做一些小的改进：|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|1736018|([%5E\x00-\x7F]%7C\w)%2B|code-block|syntax|javascript|1736019|或|1736020|([%5E\u0000-\u007F]%7C\w)%2B|1736021|此[%5E\x00-\x7F]和此[%5E\u0000-\u007F]部件允许正则表达式匹配非英文字母。|1736022|此(%7C)是逻辑or，而\w是英文字母，因此([%5E\u0000-\u007F]%7C\w)将匹配单个英文字母或非英文字母。|1736023|表达式末尾的%2B意味着它可以重复，因此整个表达式允许匹配所有英语或非英语字母。|1736024|你可以用不同的字符串测试第一个表达式，here是第二个。|1736025|entityMap|0|LINK|mutability|MUTABLE|url|https://regex101.com/r/sV8uK9/1^0|21|6|28|3|0|0|0|0|1|C|F|G|0|1|3|B|2|L|L|0|6|1|0|J|4|0|0^^$0|@$1|2|3|4|5|6|7|14|8|@$9|15|A|16|B|C]|$9|17|A|18|B|C]]|D|@]|E|$]]|$1|F|3|G|5|H|7|19|8|@]|D|@]|E|$I|J]]|$1|K|3|L|5|6|7|1A|8|@]|D|@]|E|$]]|$1|M|3|N|5|H|7|1B|8|@]|D|@]|E|$I|J]]|$1|O|3|P|5|6|7|1C|8|@$9|1D|A|1E|B|C]|$9|1F|A|1G|B|C]]|D|@]|E|$]]|$1|Q|3|R|5|6|7|1H|8|@$9|1I|A|1J|B|C]|$9|1K|A|1L|B|C]|$9|1M|A|1N|B|C]]|D|@]|E|$]]|$1|S|3|T|5|6|7|1O|8|@$9|1P|A|1Q|B|C]]|D|@]|E|$]]|$1|U|3|V|5|6|7|1R|8|@]|D|@$9|1S|A|1T|1|1U]]|E|$]]|$1|W|3|-4|5|6|7|1V|8|@]|D|@]|E|$]]]|X|$Y|$5|Z|10|11|E|$12|13]]]]

The answer given by Jeremy Ruten is great, but I think it's not exactly what Paul Wicks was searching for. If I understand correctly Paul asked about expression to match non-english words like <code>können</code> or <code>móc</code>. Jeremy's regex matches only non-english letters, so there's need for small improvement:

<pre><code>([^\x00-\x7F]|\w)+
</code></pre>

or

<pre><code>([^\u0000-\u007F]|\w)+
</code></pre>

This <code>[^\x00-\x7F]</code> and this <code>[^\u0000-\u007F]</code> parts allow regullar expression to match non-english letters.

This <code>(|)</code> is logical or and <code>\w</code> is english letter, so <code>([^\u0000-\u007F]|\w)</code> will match single english or non-english letter.

<code>+</code> at the end of the expression means it could be repeated, so the whole expression allows all english or non-english letters to match.

<a href="https://regex101.com/r/iS5jK8/1" rel="noreferrer">Here</a> you can test the first expression with various strings and <a href="https://regex101.com/r/sV8uK9/1" rel="noreferrer">here</a> is the second.

What is the easiest way to match non-ASCII characters in a regex? I would like to match all words individually in an input string, but the language may not be English, so I will need to match things like ü, ö, ß, and ñ. Also, this is in Javascript/jQuery, so any solution will need to apply to that.

Regular expression to match non-ASCII characters?

jQuery

在正则表达式中匹配非ASCII字符的最简单方法是什么？我希望逐个匹配输入字符串中的所有单词，但语言可能不是英语，因此我需要匹配ü、ö、？和ñ之类的内容。此外，这是在Javascript/jQuery中，因此任何解决方案都需要应用于此。
