You might already check Include static resources (JavaScript, CSS, fonts) article by magento team. They state that to add google font you need to update
1 | <link src="http://fonts.googleapis.com/css?family=Montserrat" src_type="url" /> |
But as a result it is not working. Correct code is
1 | <link src="https://fonts.googleapis.com/css?family=Montserrat" src_type="url" rel="stylesheet" type="text/css" /> |
It wont work without additional parameters.

Another case is when you want to specify font subset like &subset=latin,cyrillic. The solution is Replacing ampersand in the path with
1 | &amp;amp; |
The problem seems that the xml code is escaped three times. If it does not work for you, try adding or removing the amp; part as many times as needed until it works.
