Best way to encode Degree Celsius symbol into web page?
提问by Evanss
How should I encode special characters into web pages? For instance I need this symbol ℃, which I used just by copying and pasting the character as I can see it now. This worked for the desktop browsers I checked with and also on iPad and iPhone but nothing is displayed on a Blackberry I used for testing. Is there a standard best practice for this?
我应该如何将特殊字符编码到网页中？例如我需要这个符号℃，我只是通过复制和粘贴字符来使用它，就像我现在看到的那样。这适用于我检查过的桌面浏览器以及 iPad 和 iPhone，但在我用于测试的 Blackberry 上没有显示任何内容。是否有标准的最佳实践？

Try to replace it with °, and also to set the charset to utf-8, as Martin suggests.
°正如 Martin 建议的那样，尝试将其替换为, 并将字符集设置为 utf-8。
°Cwill get you something like this:
°C会给你这样的东西：

If you really want to use the DEGREE CELSIUS character “℃”, then copy and paste is OK, provided that your document is UTF-8 encoded and declared as such in HTTP headers. Using the character reference ℃would work equally well, and would work independently of character encoding, but the source would be much less readable.
如果你真的想使用摄氏度字符“℃”，那么复制和粘贴就可以了，前提是你的文档是 UTF-8 编码的，并在 HTTP 标头中声明为这样。使用字符引用℃同样可以工作，并且可以独立于字符编码工作，但源代码的可读性要差得多。
The problem with Blackberry is most probably a font issue. I don't know about fonts on Blackberry, but the font reperttheitroade might be limited. There's nothing you can do about this in HTML, but you can use CSS, possibly with @font face.
黑莓的问题很可能是字体问题。我不了解 Blackberry 上的字体，但字体库可能有限。在 HTML 中您无能为力，但您可以使用 CSS，可能还带有@font face.
But there is seldom any reason to use the DEGREE CELSIUS. It is a compatibility character, included in Unicode due to its use in East Asian writing. The Unicode Standard explicitly says in Chapter 15(section 15.2, page 497):
但很少有理由使用摄氏度。它是一个兼容字符，由于在东亚文字中使用而包含在 Unicode 中。Unicode 标准在第 15 章（第 15.2 节，第 497 页）中明确指出：
“In normal use, it is better to represent degrees Celsius “°C” with a sequence of U+00B0 degree sign + U+0043 latin capital letter c, rather than U+2103 degree celsius.”
“在正常使用中，最好用 U+00B0 度符号 + U+0043 拉丁大写字母 c 的序列来表示摄氏度“°C”，而不是 U+2103 摄氏度。”
The degree sign “°” can be entered in many ways, including the entity reference `°, but normally it is best to insert it as a character, via copy and paste or otherwise. On Windows, you can use Alt 0176.
度数符号“°”可以通过多种方式输入，包括实体引用“°”，但通常最好通过复制和粘贴或其他方式将其作为字符插入。在 Windows 上，您可以使用 Alt 0176。
Caveat: Some browsers may treat the degree sign as allowing a line break after it even when no space intervenes, putting “°” and the following “C” on separate lines. There are different ways to prevent this. A simple and effective method is this: <nobr>42 °C</nobr>.
警告：一些浏览器可能会将度数符号视为允许在它之后换行，即使没有空格介入，将“°”和后面的“C”放在单独的行上。有不同的方法可以防止这种情况发生。一个简单有效的方法是这样的：<nobr>42 °C</nobr>.

I'm not sure why this hasn't come up yet but why don't you use ℃(℃) or ℉(℉) for Celsius and Fahrenheit respectively!
我不确定为什么这还没有出现，但为什么不分别使用℃(℃) 或℉(℉) 表示摄氏和华氏！

Add a metatag to your header
将元标记添加到您的标题
<meta http-equiv="Content-Type" content="text/html;charset=utf-8" />
This expands the amount of characters you can use.
这扩大了您可以使用的字符数量。

- The degree sign belongs to the number, and not to the "C". You can regard the degree sign as a number symbol, just like the minus sign.
- There shall notbe any space between the digits and the degree sign.
- There shallbe a non-breaking space between the degree sign and the "C".
- 度数符号属于数字，而不属于“C”。您可以将度数符号视为数字符号，就像减号一样。
- 有应不为数字和符号度之间的任何空间。
- 这里应是程度的标志和“C”之间的非打破空间。
