Fonts not being loaded on WeasyPrint 53.4

[This is rather question/help request rather than current project issue, but if you can help -> thanks!]

Hey, So I wanted to update WeasyPrint from 52.5 to 53.4 on my project, and now for some reason is not loading fonts into pdf correctly (I think). I wanted to know what changed from the version to version and why it can behave like this.

WeasyPrint 53.4:

WeasyPrint 52.5:

Fonts are loaded using FontConfig, from template style.css file, and also by using font-faces like this:

@font-face {
      font-family: 'Roboto';
      src: local('Roboto'), url('{% static 'reports/avantage/fonts/Roboto-Regular.ttf' %}') format('truetype');
      unicode-range: U+0000-00FF, U+0131, U+0152-0153, U+02BB-02BC, U+02C6, U+02DA, U+02DC, U+2000-206F, U+2074, U+20AC, U+2122, U+2191, U+2193, U+2212, U+2215, U+FEFF, U+FFFD;
}

It works! I was only loading normal weight 400 fonts, when I added next types (italic/bold) it started working. Thanks!

With the CSS you shared, the Roboto font is never really called. If you want to define fonts and use them on elements, you have to do something like this (please see the example below).

Here, we define two font-face, one with Regular Roboto and one with Italic Roboto, and we say that the whole body uses Roboto. So, Roboto is used everywhere and, as we gave information about Roboto Italic, WeasyPrint is able to apply Roboto Italic on i tags.

@font-face {
  font-family: Roboto;
  src: url("Roboto-regular.ttf");
}
@font-face {
  font-family: Roboto;
  src: url("Roboto-italic.ttf");
  font-style: italic;
}

body {
  font-family: Roboto;
}

With 52.5, a false italic was generated by cairo. As we don’t rely on cairo anymore, you have to define all the font-face you need.
