Google Analytics (and other comparable services) will often be blocked by tools such as EFF's Privacy Badger. It depends on your audience how many users do this. If you want reliable metrics, analyse your webserver's access logs instead, or implement a usage logging solution that does not depend on calls to a third party domain. Fonts hosted at a third party can be blocked, but not as often as analytics services. You could simply host the WOFF files with your website. As long as you configure the webserver to serve these fonts with the proper caching headers, users should only request them once.
