CssOptimizer strips out space in quotes breaking certain kinds of CSS like content: " " which is why you see the comma-lists looking like value,value,value instead of value, value, value

Try this?

\s*([@{};,])\s*(?!")

jkochis created an issue. See original summary.

The below function in namespace Drupal\Core\Asset; is the culprit for this.

Someone good at Regex can easily fix this issue.

  public function clean($contents) {
    // Remove multiple charset declarations for standards compliance (and fixing
    // Safari problems).
    $contents = preg_replace('/^@charset\s+[\'"](\S*?)\b[\'"];/i', '', $contents);

    return $contents;
  }

Actually I believe it's processCss() line 209 of CssOptimizer.php:
\s*([@{};,])\s*
should change to:
\s*([@{};,])\s*(?!")

I don't have any tests written :) This tagging just signals that we need some tests, before we can mark this issue as RTBC.

I think this was fixed in #936316: CSS aggregation strips some essential whitespace within strings

If you are experiencing this problem on a supported version of Drupal reopen the issue, by setting the status to 'Active', and provide complete steps to reproduce the issue (starting from "Install Drupal core").

Thanks!
