regex - Anyone know how to use Regex in notepad++ to find Arabic characters?

Question

I am trying to detect Arabic characters in a webpage's HTML using Notepad++ CTRL+F with regular expressions. I am entering the following as my search terms and it is returning all characters.

[\u0600-\u06FF]

Sample block of random text I'm working with -

awr4tgagas
بqa4tq4twْq4tw4twtfwd
awfasfrw34جَ4tw4tg
دِيَّة عَرqaw4trawfَبِيَّ

Any ideas why this Regular Expression won't detect the Arabic characters properly and how I should go about this? I have the document encoded as UTF-8.

Thanks!

Answer 1

这是因为 Notepadd++ 正则表达式引擎是 PCRE，它不支持您提供的语法。

要匹配 unicode 代码点，您必须使用\x{NNNN}这样您的正则表达式变为：

[\x{0600}-\x{06FF}]

Answer 2

因为 Notepad++ 的正则表达式实现要求你使用

\x{NNNN}

符号来匹配 Unicode 字符。

在你的例子中，

\x{0628} 

可用于匹配ب(bāʾ,bet,beth,vet) 字符。

该\u符号用于匹配大写字母。
