通过浏览器支持Unicode

我正在使用。图标是使用unicode值生成的。
在此过程中，我遇到了一个问题，即某些浏览器不支持某些unicode值。因此，它显示的不是正确的图标，而是一些不需要的符号。

---

要在任何浏览器中提供Unicode支持，我们必须遵循哪些步骤

所有支持Unicode的浏览器都支持所有字符代码，但并非所有字体都有用于所有Unicode字符的字符标志符号

---

因此，要获得对所需字符的支持，您需要下载一种包含这些字符的字体，其格式由所有不同的操作系统使用。

这主要是字体问题，但如果CSS中列出的字体不包含某些字符，则不同的浏览器将以不同的方式使用回退字体。解决方法是尝试找到一个字体列表，其中可能包含您使用的所有字符。这样做的难度很大程度上取决于您使用的字符。在按钮中使用最近引入的字符几乎毫无意义，因为图像工作更可靠。在文本中使用字符是另一个问题。有关详细信息，请参见我的。

您可以使用等工具创建自己的字体

Icomoon应用程序允许您执行以下每项操作：

<!-- Method 1 -->
<!--- * * * * * * * * * * * * -->
<!-- Set a font-family for an entire HTML element -->
<!-- Define your icon fonts in your CSS font-family after your regular fonts  -->
<!-- This means that regular characters are default. Icons are a fallback  -->
<!-- Use UTF-8 characters directly in your HTML for improved human readability -->
<div class="rate"><p>I rate this movie ★★★★☆!!</p></div>

<!-- Method 2 -->

<!-- Set a font-family for an entire HTML element -->

<!-- Use entity codes in your HTML when UTF-8 support is uncertain -->
<div class="rate"><p>I rate this movie &#9733;&#9733;&#9733;&#9733;&#9734;!!</p></div>

<!-- Method 3 -->

• 从几种常用图标字体中获取一个或多个图标
• 上传其他字体，可能是图标字体，也可能是常规字体
• 从任意数量的可用字体中组合任意数量的图标
• 为需要的字符设置UNICODE十六进制值
• 导出和/或保存您创建的字体集

---

我使用Icomoon应用程序创建，并根据每个项目创建自定义图标字体

要在CSS中包含图标字体，可以包含以下代码：

@font-face {
    font-family: 'myfont';
    src:url('fonts/myfont.eot?-td2xif');
    src:url('fonts/myfont.eot?#iefix-td2xif') format('embedded-opentype'),
        url('fonts/myfont.woff?-td2xif') format('woff'),
        url('fonts/myfont.ttf?-td2xif') format('truetype'),
        url('fonts/myfont.svg?-td2xif#myfont') format('svg');
    // Different URLs are required for optimal browser support
    // Make sure to :
    // 1) replace the URLs with your font's URLs
    // 2) replace `#myfont` with the name of your font
    font-weight: normal; // To avoid the font inherits boldness
    font-style: normal; // To avoid font inherits obliqueness or italic
}

.icon {
    font-family: 'myfont', Verdana, Arial, sans-serif; // Use regular fonts as fallback
    speak: none; // To avoid screen readers trying to read the content
    font-style: normal; // To avoid font inherits obliqueness or italic
    font-weight: normal; // To avoid the font inherits boldness
    font-variant: normal; // To avoid the font inherits small-caps
    text-transform: none; // To avoid the font inherits capitalization/uppercase/lowercase
    line-height: 1; // To avoid the font inherits an undesired line-height
    -webkit-font-smoothing: antialiased; // For improved readability on Webkit
    -moz-osx-font-smoothing: grayscale; // For improved readability on OSX + Mozilla
}

图标字体如、或通常都使用方法7。这是为了避免您必须从备忘单复制粘贴特殊字符或被迫使用HTML实体

然而，这种方法有几个缺点。首先，它需要支持

：before

CSS选择器和UNICODE字符转义序列。IE6-7和IE6-7都不提供这种支持

另一个缺点是，您必须为每个图标使用单独的HTML标记，每个标记对应于图标字体中的一个字符。与其他方法不同，方法7不可能在HTML标记中显示多个图标

不过，其他方法也有自己的缺点。方法1、3和5要求您从备忘单复制粘贴字符，或使用方法将字符本身放入代码中。您的代码编辑器可能无法显示该字符，或者如果图标字体使用非标准的字符映射，它可能会显示与图标字体中的字符不同的字符

---

方法2、4和6不要求您复制粘贴字符，但是它会降低代码的可读性，并使代码的任何更改更容易出现人为错误。此外，您还需要查找要使用的每个图标的HTML实体代码，或者需要记住它们。虽然方法7中使用的类显然也是如此，但这些类比HTML实体代码更容易记忆。

有没有几乎包含所有这些字符的字体？
