SASS在Unicode内容前加反斜杠(\) [英] SASS is prepending unicode content with backslash (\)

问题描述

我正在尝试在编译* .scss文件后产生一些Unicode字符.

I'm trying to produce some unicode characters after compiling my *.scss file.

例如，我有以下(SCSS):

As an example, I have the following (SCSS):

.element:after {
    content: "\a0";
}

在编译文件时，它输出以下(CSS):

When the file is compiled, it outputs the following (CSS):

.element:after {
    content: "\\a0";
}

注意多余的反斜杠(\).

我确实在此处尝试了该解决方案: Sass:Unicode转义未保存在.css文件中，这建议引入以下功能:

I did try the solution here: Sass: unicode escape is not preserved in .css file, which suggests introducing the following function:

@function unicode($str) {
    @return unquote("\"")+unquote(str-insert($str, "\\", 1))+unquote("\"")
}

并像这样(SCSS)使用它:

And using it like so (SCSS):

.element:after {
    content: unicode("a0");
}

但是，这会产生以下(CSS)

However, this produces the following (CSS)

.element:after {
    content: "\\" ")+unquote(str-insert($str, " \\\\ ", 1))+unquote(" \\ ""; 
}

注意，它甚至没有按预期调用功能.为什么会这样?

我正在Maven中使用这些库:

I'm using these libraries in Maven:

<dependency>
    <groupId>net.jawr</groupId>
    <artifactId>jawr-core</artifactId>
    <version>3.9</version>
</dependency>

<dependency>
    <groupId>net.jawr.extensions</groupId>
    <artifactId>jawr-spring-extension</artifactId>
    <version>3.9</version>
</dependency>

<dependency>
    <groupId>com.darrinholst</groupId>
    <artifactId>sass-java-gems</artifactId>
    <version>3.4.20.0</version>
</dependency>

<dependency>
    <groupId>org.jruby</groupId>
    <artifactId>jruby-core</artifactId>
    <version>9.1.5.0</version>
</dependency>

<dependency>
    <groupId>org.jruby</groupId>
    <artifactId>jruby-stdlib</artifactId>
    <version>9.1.5.0</version>
</dependency>

临时解决方案

请勿在SCSS中使用unicode.而是在HTML中使用Font Awesome(在CSS文件中保留Font Awesome).

Temporary solution

Don't use unicodes in SCSS. Instead, use Font Awesome in the HTML (keeping Font Awesome in a CSS file).

推荐答案

在尝试使用自定义图标字体时，我遇到了同样的问题.我发现的解决方案是创建一个看起来像这样的mixin:

I had the same issue while trying to use a custom icons font. The solution I found is creating a mixin which looks like this :

@mixin class-for-icon($name, $code) {
    .icon-#{$name}::before {
        content: unquote("\"\\#{$code}\"");
    }
}

然后我可以像这样使用它:

And then I can use it like this :

@include class-for-icon('myIcon', 'e1ff');

/* generates */

.icon-myIcon::before {
    content: "\e1ff";
}

我使用node-sass 4.5.3将sass文件编译为css，并且运行良好(当前在一些项目的生产环境中使用它)

I use node-sass 4.5.3 to compile my sass files into css, and this is working well (currently using it in production on a few projects)
