If you are using Spring MVC with Spring Security, Spring Security automatically adds no cache headers and so causes font-awesome to break on IE11.

(https://docs.spring.io/spring-security/site/docs/current/reference/html/headers.html#headers-cache-control)

I solved the issue by adding a ResourceHandler in my WebMvcConfiguration for font-awesome configured to allow the browser to cache the fonts.

public class WebMvcConfiguration extends WebMvcConfigurerAdapter
{
    @Override
    public void addResourceHandlers( ResourceHandlerRegistry registry )
    {
        registry.addResourceHandler("/assets/vendor/font-awesome/fonts/**")
            .addResourceLocations("/assets/vendor/font-awesome/fonts/")
            .setCachePeriod(31556926);        
    }
}
