Parcel: Parcel remove quote characters on production build css

[tung-eh]

🐛 bug report

Parcel remove single quote on production build css

🎛 Configuration (.babelrc, package.json, cli command)

I add a css file like this

    <link href="./index.css" rel="stylesheet">

In index.css, I define a font with some spaces in its name

@font-face {
  font-family: 'Quarz 974';
  src: url('/assets/fonts/quarz974/Quarz 974 Light.woff') format('woff');
}

🤔 Expected Behavior

The css stay the same or maybe replace single quotes with double quotes

😯 Current Behavior

Quote characters around font name and font url have been gone

@font-face{font-family:Quarz\ 974;src:url(/Quarz 974 Light.0eb3ffef.woff) format("woff")}

💁 Possible Solution

I don't know what is going on

🔦 Context

It just happens when run parcel build
parcel watch and parcel will work normally by generating following css

@font-face {
  font-family: "Quarz 974";
  src: url("/Quarz 974 Light.d8e445c3.woff") format('woff');
}

This is probably a minification by cssnano

@DeMoorJasper Thanks for that, I've resolved this issue by adding cssnano.config.js

module.exports = {
  preset: [
    'default',
    {
      minifyFontValues: {
        removeQuotes: false,
      },
      normalizeUrl: false,
    },
  ],
};
