如何匹配Unicode元音？

Question

什么字符类或Unicode属性将匹配Perl 中的任何Unicode元音？

错误答案:[aeiouAEIOU].(这里的讲道,洗衣清单中的第24项)

perluniprops仅为Hangul和印度语脚本提及元音.

让我们抛开一个元音是什么的问题.是的,i在某些情况下可能不是元音.所以,任何可以作为元音的角色都可以.

没有这样的财产.

处理i18n时最重要的事情是考虑你真正需要的东西,但你甚至没有提到你想要完成的事情.

找元音？这不可能是你真正想做的事情.我可以看到,用于识别元音用声音一个字,但这些往往是由多个字母(如"OO"的英文和"IN","一个" /"恩","OU"形成,"AI" ,"au"/"eau",法语中的"eu",它将是语言特定的.

就目前而言,您要求的是全球解决方案,但您要用本地术语来定义问题.首先,您需要从定义要解决的实际问题开始.
