The advantage to using these commands rather than \cmd\newfontfeature\ (see \vref{sec:newfeatures}) is the error-checking that is performed when the script or language is requested. +Both commands accept a comma-separated list of OpenType tags in order of preference. +This permits, for example, supporting both new and old versions of a language tag with +a common user interface: +\begin{Verbatim} + \newfontlanguage{Turkish}{TRK,TUR} +\end{Verbatim} +Here, a font that is requested with \verb|Script=Turkish| will first be checked for the +OpenType language tag \verb|TRK|, which will be selected if available.
