I agreed with your opinion on Postscript.

However, as shown in the attached plots in previous post, the glyph 
metric info for any CID-keyed font is based on assumption in R. In fact, 
it's not possible to get the metric info of a CID-keyed font without 
accessing the actual font which may be in truetype or opentype/CFF 
format. And, I don't think R could find the actual font.
