# After a little bit of research it turns out that google can return
# single .ttf file if User-Agent header will not contain
# **AppleWebKit/537 Chrome/74**. That is when opening url from browser
# google will return css with a bunch of .woff2 files, but requesting
# the same url with curl google will return a css with single .ttf
# file.
