Question No mime type for TTF in nginx mime.type is it normal?

[blueberry]

I have found that my ttf files were returned with mime type octet-stream instead of font/ttf
Then, I have found the config file for mime types under /etc/nginx/mime.types

No mime types are configured for ttf (trutypes fonts)

So, i have added font/ttf ttf;
to mime.types

what do you think?
