## Discussion

\abstract The language identifier for font fallback selection.
\discussion The value associated with this key is a CFStringRef. If specified in a font descriptor, it is used to select the appropriate font fallback list for the language. This key should not be confused with kCTLanguageAttributeName, which is defined in CTStringAttributes.h.
