Explainer None Specification https://www.w3.org/TR/css-fonts-4/#font-language-override-prop Summary This feature introduces support for the font-language-override CSS property in Chromium. The property allows developers to override the system language used for OpenType glyph substitution by specifying a four-character language tag directly in CSS. This enables fine-grained typographic control, particularly useful for multilingual content or fonts with language-specific glyph variants.
