在 actionscript 正则表达式中指定 unicode 范围 [英] Specifying a unicode range in an actionscript regular expression

问题描述

我一直在尝试编写一个正则表达式来匹配所有 unicode 单词字符，例如:

I have been trying to write a regular expression that would match all unicode word character something like :

/[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF\w]/gi

但这完全失败并且不匹配任何东西.我尝试了各种表达式，似乎只要我尝试指定一个范围，它就会失败.有人比我幸运吗?

But this completely fails and doesn't match anything. I have tried a variety of expressions and it seems that as soon as I try to specify a range it fails. As anyone been luckier than me?

我希望 actionscript 能提供类似 \p{L} 的东西，但如果有类似的东西，我在文档中找不到它.

I wish actionscript would offer something like \p{L}, but if there's anything in the like, I couldn't find it in the doc.

推荐答案

您可以将 String.fromCharCode 与 unicode 字符一起使用，然后范围将在正则表达式中正常工作.以下是使用原始问题的示例:

You can use String.fromCharCode with the unicode characters and then the ranges will work correctly in a regular expression. Here is an example using your original problem:

var exp:RegExp = new RegExp("[" + generateRangeForUnicodeVariables(0x00A0, 0xD7FF) + generateRangeForUnicodeVariables(0xF900, 0xFDCF) + generateRangeForUnicodeVariables(0xFDF0, 0xFFEF) + "\w]", "gi");

private function generateRangeForUnicodeVariables(var1:Object, var2:Object):String
{
   return String.fromCharCode(var1) + "-" + String.fromCharCode(var2);
}
