    config.module.rules.filter(rule => {
      return rule.test.toString().indexOf("scss") !== -1;
    })
      .forEach(rule => {
        rule.oneOf.forEach(oneOfRule => {
          const sassLoaderIndex = oneOfRule.use.findIndex(item => item.loader === sassLoader);
          oneOfRule.use.splice(sassLoaderIndex, 0,
            { loader: require.resolve("css-unicode-loader") });
        });
      });
    }

// webpack.config.js
module.exports = {
  ...
  module: {
    rules: [{
      test: /\.scss$/,
      use: [{
          loader: "style-loader" // Creates `style` nodes from JS strings
      }, {
          loader: "css-loader" // Translates CSS into CommonJS
      }, {
          loader: "css-unicode-loader" // Convert double-byte character to unicode encoding.
      }, {
          loader: "sass-loader" // Compiles Sass to CSS
      }]
    }]
  }
