fonts: Support `font-language-override` by simonwuelker · Pull Request #46618 · servo/servo

simonwuelker · 2026-07-18T19:48:05Z

Testing: New tests start to pass
Depends on servo/stylo#429

simonwuelker · 2026-07-18T19:49:51Z

        let font_style = parent_style.clone_font();
        let language = font_style._x_lang.0.parse().unwrap_or(Language::UND);
+        let language_for_shaping = Some(font_style.font_language_override)
+            .filter(|language_override| *language_override != FontLanguageOverride::normal())


We differentiate between language and language_for_shaping here because it is my understanding that font-language-override should not affect font selection. The specification is not really explicit about that though: https://drafts.csswg.org/css-fonts/#font-language-override-prop

We should actually stop using the Language type when shaping due to #44430.
