Latin characters dont work from custom font

Hi, I have problem with latin characters like ě ? ? ? ? on my site. I use custom font champagne and limousines
https://www.ceskefonty.cz/ceske-fonty/champagne-limousines
Font has latin characters, but for some reason they dont work on website (they are being shown in different font).

this is code from style.css

to load the font
@font-face {
font-family: ‘champagne__limousinesregular’;
src: url(‘https://greengrill.cz/fonts/Champagne_Limousines-webfont.eot’);
src: url(‘https://greengrill.cz/fonts/Champagne_Limousines-webfont.eot?#iefix’) format(’embedded-opentype’),
url(‘https://greengrill.cz/fonts/Champagne_Limousines-webfont.woff2’) format(‘woff2’),
url(‘https://greengrill.cz/fonts/Champagne_Limousines-webfont.woff’) format(‘woff’),
url(‘https://greengrill.cz/fonts/Champagne_Limousines-webfont.ttf’) format(‘truetype’),
url(‘https://greengrill.cz/fonts/Champagne_Limousines-webfont.svg#champagne__limousinesregular’) format(‘svg’);
font-weight: normal;
font-style: normal;

}

to use it
font-family: ‘champagne__limousinesregular’;

website is not connected to domain yet, but you can see it at
217.16.185.183 greengrill.cz

any advice would be much appreciated
