Using AFP metrics in mapped font

You can map AFP fonts by specifying to use the AFP metrics instead of the metrics of the mapped font. Specify the Use_AFP_metrics config file entry together with changes in the fontfile. The value specified by the Use_AFP_metrics must be in the 0-255 range. The fontfile must contain an entry for each font that uses AFP Metrics where it is specified the name (Character Set name) and the same value in hexadecimal notation that was specified in the Use_AFP_metrics config file entry. For example, if Use_AFP_metrics=255, the afpfont file is C0RAST01 FF.
