规范标签和UTF8
以下 2 个规范链接标签会被蜘蛛视为指向同一个 URL 吗？
- 编码 - 未编码
Would the following 2 canonical link tags be viewed by spiders as pointing to the same URL?
<link rel="canonical" href="http://www.example.com/ŷ" /> - encoded<link rel="canonical" href="http://www.example.com/ŷ" /> - unencoded

ŷ是一个 HTML 实体，以十进制表示法表示代码点为 375 的 Unicode 字符。在十六进制中它是 0x177，所以我们讨论的是 U+0177，即ŷ。这意味着两个 URL 完全相同，如果：
如果浏览器在这两种情况下都显示 ŷ，则字符集可能是正确的，但您应该确保它是正确的。
ŷis an HTML entity that represents the Unicode character with code point 375 in decimal notation. In hexadecimal it'd be 0x177 so we are talking about U+0177 which isŷ.That means that both URLs are exactly the same if:
If the browser displays ŷ in both cases it's likely that character set is correct but you should make sure it is.
如果您将 HTML 作为 UTF-8 进行通信，则 url 会被视为相同。
if you communicate your HTML as UTF-8 the url is seen as the same.
不是 100% 确定，但我认为它们都指向相同的 URL。但请记住，查看 W3 标准时，他们经常建议对链接进行编码。
Not 100% sure, but I think they both would point to the same URL. But keep in mind, that looking at W3 standards, they often suggest links to be encoded.
尽管您可以期望它在现代浏览器中工作，
http://www.example.com/ŷ是一个无效的 URL。您应该始终对 unicode 字符进行百分比编码。
Even though you can expect it to work in modern browsers,
http://www.example.com/ŷis an invalid URL.You should always percent encode unicode characters.
