我应该使用什么字符编码用于包含大部分阿拉伯文字的网页？是utf-8好吗？ [英] What character encoding should I use for a web page containing mostly Arabic text? Is utf-8 okay?

问题描述

是utf-8还好吗？

解决方案

UTF-8可以存储完整的Unicode范围，因此可以使用阿拉伯语。

但是，如果您想知道哪种编码最有效： b
$ b

所有阿拉伯字符都可以使用一个UTF-16编码单元进行编码（2字节），但它们可以采用2或3个UTF-8代码单元（每个1字节），所以如果你只是编码阿拉伯语，UTF-16将是一个更节省空间的选择。

然而，你不只是编码阿拉伯文 - 你编码了大量的字符，可以用UTF-8单个字节存储，但UTF-16需要两个字节;所有html编码字符< ，& ，> ， = 以及所有html元素名称。

这是一种折衷，除非你处理与巨大的文件，没关系。

Is utf-8 okay?

解决方案

UTF-8 can store the full Unicode range, so it's fine to use for Arabic.

However, if you were wondering what encoding would be most efficient:

All Arabic characters can be encoded using a single UTF-16 code unit (2 bytes), but they may take either 2 or 3 UTF-8 code units (1 byte each), so if you were just encoding Arabic, UTF-16 would be a more space efficient option.

However, you're not just encoding Arabic - you're encoding a significant number of characters that can be stored in a single byte in UTF-8, but take two bytes in UTF-16; all the html encoding characters <,&,>,= and all the html element names.

It's a trade off and, unless you're dealing with huge documents, it doesn't matter.
