I have a website with custom font that is stored locally on server, and is defined in CSS file: @font-face {

   font-family: 'quicksandlight';
   src:  url('/static/fonts/Quicksand-VariableFont_wght.ttf') format('truetype'),
         url('/static/fonts/quicksand-variablefont_wght-webfont.woff2') format('woff2'),
         url('/static/fonts/quicksand-variablefont_wght-webfont.woff') format('woff');
   font-weight: normal;
   font-style: normal;

} Chrome is showing all letters in this font, and Edge and Firefox are showing most letters correct, but not B, D, T, P, R and X. What I know is that this is only happening on words that have "font-weight: bold" or "font_weight: 600", when it's set "font-weight: 400" all letters are renderd correctly. This is bugging me af, and if somebody can help to fix this, without need to change to lower font-weight, I would appreciate it.

Do you have specific @font-face rules for heavier weights? For example:

@font-face {
  font-family: 'Open Sans';
  font-style: normal;
  font-weight: 400;
  font-display: fallback;
  src: local('Open Sans'), local('Open Sans Regular'), local('OpenSans-Regular'), url(fonts/opensans.woff2) format('woff2');
  unicode-range: U+0000-00FF, U+0131, U+0152-0153, U+02C6, U+02DA, U+02DC, U+2000-206F, U+2074, U+20AC, U+2212, U+2215;
}
@font-face {
  font-family: 'Open Sans';
  font-style: normal;
  font-weight: 700;
  font-display: fallback;
  src: local('Open Sans Bold'), local('OpenSans-Bold'), url(fonts/opensansbold.woff2) format('woff2');
  unicode-range: U+0000-00FF, U+0131, U+0152-0153, U+02C6, U+02DA, U+02DC, U+2000-206F, U+2074, U+20AC, U+2212, U+2215;
}

According to MDN, bold generally equates to font-weight: 700, so browsers may be improvising with font-weight: 600. You might need to add a few more rules to help browsers that aren't improvising as successfully.

But I'm most definitely not an expert on on fonts. We have this article if the forum isn't able to get to the bottom of it: Where to go for developer support.

Issue was as jscher2000 pointed out, I had to specify font-face for different font-weight (in my case bold), and then FF was rendering it correctly. Thanks a lot for help!
