  Unicode(统一码、万国码、单一码)是一种在计算机上使用的字符编码。它为每种语言中的每个字符设定了统一并且唯一的二进制编码,以满足跨语言、跨平台进行文本转换、处理的要求。 Unicode Character Table 包含常见语言的字符和可打印的符号字符,字符提供了 HTML 代码,名称/描述和相应的打印符号。 您可能感兴趣的相关文章 Verlet-js:超炫的开源 JavaScript 物理引擎推荐 Transit – 超平滑的 CSS 过渡和变换动画效果插件 Debuggex – 超好用的正则表达式可视化调试工具 -prefix-free:帮你从 CSS 前缀的地狱中解脱出来 Zepto.js – 为现代浏览器而生的轻量JavaScript库 去围观 您可能感兴趣的相关文章 OverAPI.com – 史上最全开发人员在线速查手册 CSS Matic:网页设计师必备的终极 CSS 工具箱 CSS Beautify – 方便的在线 CSS 代码美化工具 ScrollUp – 超轻量可定制的回到顶部jQuery插件 Swipebox – 用于触屏的 jQuery Lightbox 插件 本文链接: Unicode Character Table – 完整的Unicode字符表 编译来源: 梦想天空 ◆ 关注前端开发技术 ◆ 分享网页设计资源 来源: https://www

转: http://www.utf.com.cn/article/s1383 这些相关的东西并不复杂, 但非常容易混淆不清, 尤其是最近看了一些这方面的文章, 即使是被认为是权威的出处, 也经常出现冲突矛盾, 和用词不准确, 解释的概念不清楚的情况: 1. 字符集和编码方案混为一谈. http://www.utf.com.cn/article/s320 中说: UTF_8字符集 UTF-8是UNICODE的一种变长字符编码 后一句话对, 但前一句话, UTF-8是对Unicode字符集的可能的编码方案中的一种, 它本身不是字符集. 2. 字符集只是字义了一个虚拟的, 与电脑无关的一个字符的集合, 规定了在这些集合里面就有哪些字符, 每个字符被赋予一个编号, 编号不是编码, 编号是Unicode术语中的code point的概念, 这些字符就外在的人眼所能看到的形状而言不必是唯一的. 3. Unicode给每个字符赋予的唯一的code point, 只是一个数学概念上的数字, 不要与计算机里对数值的某种表示法联系起来, 还没到那一步, 那是由编码方案决定的. 这个概念上的数, 在Joel on software里的那篇文章" The Absolute Minimum Every Software Developer Absolutely, Positively Must Know

If 'ℤ' is in the BMP, why isn't it encoded in 2 bytes?

问题 My question arises from this answer, which says: Since 'ℤ' (0x2124) is in the basic multilingual plane it is represented by a single code unit. If that's correct, then why is "ℤ".getBytes(StandardCharsets.UTF_8).length == 3 and "ℤ".getBytes(StandardCharsets.UTF_16).length == 4 ? 回答1: It seems you're mixing up two things: the character set (Unicode) and their encoding (UTF-8 or UTF-16). 0x2124 is only the 'sequence number' in the Unicode table. Unicode is nothing more than a bunch of 'sequence

阅读过不少关于mysql的编码设置和乱码问题的一些文章,经过再三的调试,终于通过,终于解决了一块心病,终于解了我心头之恨,哈哈哈。现在把它概括如下。 MySQL 4.1的字符集支持(Character Set Support)有两个方面:字符集(Character set)和排序方式(Collation)。对于字符集的支持细化到四个层次: 服务器(server),数据库(database),数据表(table)和连接(connection)。我们最终的目标是使得这四个层次转化会支持中文的编码,下面以utf8为例。 1. 首先查看系统的字符集和排序方式。如果想查看某个特定的数据库的字符集和排序方式,应该先选定数据库,mysql>use databasename; mysql> SHOW VARIABLES LIKE ''character_set_%''; +--------------------------+----------------------------+ | Variable_name | Value | +--------------------------+----------------------------+ | character_set_client | latin1 | | character_set_connection | latin1 | |

问题 I have a scraper that is collecting some data from elsewhere that I have no control over. The source data does all sorts of interesting Unicode characters but it converts them to a pretty unhelpful format, so \u00e4 for a small 'a' with umlaut (sans the double quotes that I think are supposed to be there)*. of course this gets rendered in my HTML as plain text. Is there any realistic way to convert the unicode source into proper characters that doesn't involve me manually crunching out every
