metrics = pcontext:GetMetrics(desc, language)

Since the metrics may be substantially different for different scripts, a language tag can be provided to indicate that the metrics should be retrieved that correspond to the script(s) used by that language.

The Pango font description is interpreted in the same way as by pcontext:Itemize(), and the family name may be a comma separated list of names. If characters from multiple of these families would be used to render the string, then the returned fonts would be a composite of the metrics for the fonts loaded for the individual families.

This function returns a Pango font metrics object. The caller must call pfontmetrics:Free() when finished using the object.

language
