TTF not gzipped

Hello,

I am not sure if that could be a bug or it is works like this by design, but it seems that TTF files are no gzipped.

I am not sure if that is related to SG Optimizer or to SG NGIX configuration.

In our page we load 2 TTF resources:
/wp-content/themes/Divi/core/admin/fonts/modules.ttf 92.7kB
/wp-content/uploads/et-fonts/BebasNeue-Regular.ttf 60.9kB

GZIP them should reduce to 36.6 kB and 26.7kB respectively.

I tried to add the rule to .htaccess manually, but it seems ignored.

Any suggestions?
