 As per the [https://make.wordpress.org/core/handbook/best-practices
 /coding-standards/css/#values CSS Coding standards]:

 Values:
 Use double quotes rather than single quotes, and only when needed, such as
 when a font name has a space.

 Specifically, for CSS generated content (especially icons) there are good
 reasons to always use double quotes, see [34011] / #33786. Even when the
 icons don't have to be swapped for RTL, using double quotes it's always a
 good practice.

 I'd also propose to update the Coding Standards page to explicitly mention
 values for the `content` property.
