29167	HashedFilesMixin doesn't work with data URIs that include a closing parenthesis	Clem Flory	Adam Zapletal	"My team recently started using Bootstrap 4, and some of their styles get broken by the regex patterns in `HashedFilesMixin` (https://github.com/django/django/blob/2.0.2/django/contrib/staticfiles/storage.py#L52-L57).  This is loosely related to #21080.

For example, this is one of the rules in the generated Bootstrap 4 CSS, and the current regex incorrectly mistakes the closing parentheses in `rgba(0, 0, 0, 0.5)` as the end of `url()`:
{{{#!css
.navbar-light .navbar-toggler-icon {
  background-image: url(""data:image/svg+xml;charset=utf8,%3Csvg viewBox='0 0 30 30' xmlns='http://www.w3.org/2000/svg'%3E%3Cpath stroke='rgba(0, 0, 0, 0.5)' stroke-width='2' stroke-linecap='round' stroke-miterlimit='10' d='M4 7h22M4 15h22M4 23h22'/%3E%3C/svg%3E"");
}
}}}

Not an ideal solution, but we were able to work around this issue by Base64 encoding these data URIs."	Bug	closed	contrib.staticfiles	2.0	Normal	worksforme		Adam Zapletal	Unreviewed	1	0	0	0	0	0
