问题描述
我需要确定我的输入属于哪种自然语言.目标是区分混合输入中的 阿拉伯语 和 英语 单词，其中输入是 Unicode 并从 XML 文本节点中提取.我注意到类 Character.UnicodeBlock.和我的问题有关吗?我怎样才能让它工作?
I need to identify what natural language my input belongs to.
The goal is to distinguish between Arabic and English words in a mixed input, where the input is Unicode and is extracted from XML text nodes.
I have noticed the class Character.UnicodeBlock. Is it related to my problem? How can I get it to work?
Character.UnicodeBlock 方法对阿拉伯语很有用，但显然不适用于英语(或其他欧洲语言)，因为 BASIC_LATIN Unicode 块涵盖符号和不可打印字符和字母.所以现在我使用 String 对象的 matches() 方法和正则表达式 "[A-Za-z]+" 代替.我可以忍受它，但也许有人可以提出更好/更快的方法.
The Character.UnicodeBlock approach was useful for Arabic, but apparently doesn't do it for English (or other European languages) because the BASIC_LATIN Unicode block covers symbols and non-printable characters as well as letters.
So now I am using the matches() method of the String object with the regex expression "[A-Za-z]+" instead. I can live with it, but perhaps someone can suggest a nicer/faster way.
推荐答案
是的，你可以简单地使用 Character.UnicodeBlock.of(char)
Yes, you can simply use Character.UnicodeBlock.of(char)
