Google fonts generate too much styles

Hello,
After setting individual Google fonts to Text, Menu and Headings, I got a lot of style entries like this:
@font-face {
font-family: ‘Roboto’;
font-style: normal;
font-weight: 400;
src: local(‘Roboto’), local(‘Roboto-Regular’), url(https://new.gorbachevclinic.ru/wp-content/fonts/roboto/KFOmCnqEu92Fr1Mu72xMKTU1Kvnz.woff) format(‘woff’);
unicode-range: U+0460-052F, U+1C80-1C88, U+20B4, U+2DE0-2DFF, U+A640-A69F, U+FE2E-FE2F;
}

Also created styles for /* greek */ and /* vietnamese */ characters. Pointless, I use only cyrillic and latin characters.
It’s bother, because it makes page much heavier. Is it possible to avoid such behavior?
Thank you
