如何匹配Unicode元音? [英] How to match Unicode vowels?

问题描述

什么字符类或Unicode属性将与Perl中的任何 Unicode 元音匹配?

What character class or Unicode property will match any Unicode vowel in Perl?

错误答案:[aeiouAEIOU]. (在此处进行布道，衣物清单中的第24条)

Wrong answer: [aeiouAEIOU]. (sermon here, item #24 in the laundry list)

perluniprops 仅提及了韩文和印度文的元音.

perluniprops mentions vowels only for Hangul and Indic scripts.

让我们搁置一个问题，什么是元音.是的，在某些情况下i可能不是元音.因此，可以是元音的任何字符都可以.

Let's set aside the question what a vowel is. Yes, i may not be a vowel in some contexts. So, any character that can be a vowel will do.

推荐答案

没有此类属性.

处理i18n时，最重要的事情是思考您实际需要的内容，但是您甚至没有提到要完成的任务.

The most important thing when dealing with i18n is to think about what you actually need, yet you didn't even mention what you are trying to accomplish.

找到元音?那根本不是你真正想做的.我可以看到一个用于识别单词中元音 的用法，但是这些发音通常是由多个字母组成的(例如英语中的"oo"，"in"，"an"/"en"， "ou"，"ai"，"au"/"eau"，"eu"(法语)，并且它是特定于语言的.

Find vowels? That can't be what you are actually trying to do. I could see a use for identifying vowel sounds in a word, but those are often formed from multiple letters (such as "oo" in English, and "in", "an"/"en", "ou", "ai", "au"/"eau", "eu" in French), and it would be language-specific.

就目前而言，您正在寻求一个整体解决方案，但您正在用本地术语来定义问题.首先，您需要先定义要解决的实际问题.

As it stands, you're asking for a global solution but you're defining the problem in local terms. You first need to start by defining the actual problem you are trying to solve.
