Enum style::values::specified::font::FontLanguageOverride

pub enum FontLanguageOverride {
    Normal,
    Override(Box<str>),
    System(SystemFont),
}

Allows authors to explicitly specify the language system of the font, overriding the language system implied by the content language

Variants

Normal

When rendering with OpenType fonts, the content language of the element is used to infer the OpenType language system

Override(Box<str>)

Single three-letter case-sensitive OpenType language system tag, specifies the OpenType language system to be used instead of the language system implied by the language of the element

System(SystemFont)

Use system font
