# CTFontDescriptorCopyLocalizedAttribute(_:_:_:) Returns a localized value for the requested attribute, if available. ``` func CTFontDescriptorCopyLocalizedAttribute(_ descriptor: CTFontDescriptor, _ attribute: CFString, _ language: UnsafeMutablePointer?>?) -> CFTypeRef? ``` ## Parameters `descriptor` The font descriptor. `attribute` The requested font attribute. `language` On output, contains a reference to the matched language. The language identifier will conform to the RFC 3066bis standard. ## Return Value A retained reference to a localized attribute based on the global language list. ## Discussion This function passes back the matched language in `language`. If localization is not possible for the attribute, the behavior matches the value returned from [`CTFontDescriptorCopyAttribute(_:_:)`](/documentation/CoreText/CTFontDescriptorCopyAttribute(_:_:)). Generally, localization of attributes is applicable to name attributes of only a normalized font descriptor. --- Copyright © 2026 Apple Inc.
